  Acryl group - Wikipedia, the free encyclopedia
The acryl group is one of the functional groups sorted in the chemical class of acryl where one of four hydrogen atoms in ethene is replaced with a different functional group.
The word acryl as prefix instead of vinyl as noun is used when the substituting functional group is particular one.
For example, vinyl group bonding with nitrile group is called acrylonitrile but not vinyl nitrile, adding -onitrile after acryl- for the name of the acryl compounds.

While he and the future members of the Group denied any foreign influences and insisted that they were reacting to their national landscape in a completely unique way, the tree's similarity to the clumped shapes and whiplash lines of Art Nouveau is more than striking.
During the next 13 years, the Group of Seven were constantly in the press, rebutting the critics, raising Canadian's awareness of the beauty of their country, and insisting that the Canadians support Canadian art.
In 1933 the Group was dissolved and reformed into the larger Canadian Group of Painters, but across much of Canada, or at least, across English speaking Canada, people still consider the Group of Seven to be their national school.

 INABIS '98 - Problems of Occupational Medicine in Acryl Compounds Production.
Acryl compounds are: acryl acid, methacryl acid (MAA); their derivates (ethers, amides, nitriles and others); polymers and co-polymers on their base.
It was established that workplace air at acryl monomers producing plants was polluted by mixture of chemicals, mainly with acryl and methacryl acids or their ethers and alcohols (methyl and butyl alcohols).
Workplace air MACs for more than 30 acryl monomers and chemicals used for their synthesis were establised on the base of toxicological, hygienic and clinical studies data.

 Painting with Testor's Acryl
Acryl's high degree of self-leveling means it flows more smoothly and dries more evenly for a "flatter" flat finish.
Acryl is tough and durable, but remember: since formulations for other hobby paints may change, always test for overcoat compatibility on scrap before moving on to valuable model parts.
Acryl figure paints represent a challenge because they must balance the fine line between thick and thin, providing adequate coverage and yet not masking detail.

Preferably, the functional acryl groups are attached to the terminal ends of polysiloxane molecules, as exemplified by acrylamidopropyl-, methacrylamidopropyl-, acryloxyhexyl-and methacryloxyhexyl- terminated polysiloxanes.
In the same manner it is also to be understood that the meaning of acryl group should include acryl or substituted acryl, such as methacryl, moieties attached through a variety of linkages including ester, amide and urethane linkages, or functional analogues of acryl capable of undergoing crosslinking reactions with a photoinitiator.
According to one embodiment, the polysiloxane is a copolymer of diphenyl or phenylalkyl siloxane and dialkyl siloxane with terminal acryl groups.

R.sub.2 is a substituted or unsubstituted anilino group, an acylamino group (e.g., an alkylcarbonamido group, a phenylcarbonamido group, an alkoxycarbonamido group and a phenyloxycarbonamido group), or a ureido group (e.g., an alkylureido group and a phenylureido group) and preferably is acylamino group.
These atoms are bound to an alkyl group, an aryl group, an alkylsulfonyl group, an arylsulfonyl group, an alkylcarbonyl group, an arylcarbonyl group, or a heterocyclic group (the alkyl group, the aryl group and the heterocyclic group may have the groups shown as the substituent of the aryl group for Ar).
In formula (V), it is preferred that R.sub.3 be a halogen atom, a sulfonyl group, a sulfonamido group, a sulfamoyl group, a polyfluoroalkyl group, an acyl group, an alkoxycarbonyl group, or an acylamino group, l is 1 or 2, and the substituent be located in the m- or p-position relative to the ureido group.

It is particularly preferred to have as the reactive group a hydroxyl group alone or in combination with other reactive groups in the molecule of the polymer (b) for readily heat-curing the carbonaceous material to be obtained when the carbonaceous material is mixed with various curing agents.
The hydroxyl group may be the hydroxyl group in the molecule of the polymer (b) which remains after the contacting reaction, or may be a hydroxyl group added to the carbonaceous material after the contacting reaction.
In this case, when the compound has two substituted mercapto groups, either of the mercapto groups may be substituted by an alkyl group, an aralkyl group, or a phenyl group, or the compound may be a dimer in the form of disulfide.

 TAKING ON INDUSTRY / Group goesafter owners of new chemical plant
In its highest-profile effort yet, the group staged an Austin news conference last week, complete with overtones of presidential politics, to amplify its call for a moratorium on all new state air pollution permits in the Houston region, needed for new industrial construction.
The group and allies were scheduled to seek additional publicity for the cause on Saturday with a march to the proposed plant site.
County officials decided not to oppose state permits for the American Acryl plant after those issues were resolved and the company agreed to include certain provisions that county officials wanted in the permits, said Cathy Sisk, bureau chief for environmental and community protection in the Harris County Attorney's Office.

In group C (bipolar mode), however, mean initial impedance was less than 100Ω, but rose intermittently to more than 700Ω within approximately 4-6 mins of the instillation of RF energy.
In groups A and B, mean final-temperature values were 65+/- 10 degrees C and 81+/-8 degrees C, respectively, and in group C, 85+/- 13 degrees C. This value was higher in groups B and C than in group A (p < 0.05).

 Resinous composition for coating use - Patent 5066720
(b) 97 to 30% by weight of hydroxyl group containing resin having a hydroxyl value of 20 to 300, and (c) crosslinking agent which is reactive with a hydroxyl group This composition is particularly useful in the area where durability and weather resistance of the formed coating are specifically required.
In this invention, the functional groups contained in the crosslinking agent are reacted with hydroxyl groups of said polysiloxane and hydroxyl group containing resin, thereby resulting in a three dimensionally crosslinked polymer structure having improved mechanical strength.
Whereas, in the present invention, crosslinking occurs between the functional groups of the crosslinking agent and hydroxyl groups of the polysiloxane and of the organic resin, and therefore, the bonding included in the crosslinking is either one of ester bonding, ether bonding and urethane bonding, which are stable and hardly affected by hydrolysis.

 SECESSION
When the Canadian group of artists called General Idea exploited a painting by Robert Indiana's titled 'Love' as a composition model and substituted the old four-letter-word of the newer AIDS, critics debated not only the validity of this artistic technique but also fretted about horror being transformed into mere banality.
Methodically speaking, AA Bronson carries on the technique of General Idea: the group, which was founded in 1969, delighted in confronting the public with so-called 'taboo' subjects and were to discover new facets in symbols so worn out as to become almost unnoticeable.
Although a number of editions of the group are being produced up to the present day, AA Bronson has decided to continue his work only as a single artist.

The invention provides an active energy ray-curable composition which can be prepared from easily available raw materials, which has excellent coating properties, and which forms, when cured, a coat having a good adhesion to a polyolefin, and a method for forming the coat using the composition.
That is, the invention is an active energy ray-curable composition containing a reaction product between an isocyanate compound having an isocyanate group bound to a non-aromatic hydrocarbon ring and a (meth)acryl compound having a (meth)acryloyl group and being capable of reacting with an isocyanate group, and a method for forming a coat using the composition.
The reaction time is usually about 3 to 8 hours, but it is preferred to trance the content of isocyanate group in the reaction solution by analysis and discontinue the reaction at a point when the content reaches the intended level.
