  Acrylonitrile butadiene styrene - Wikipedia, the free encyclopedia
It is a copolymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene.
Acrylonitrile butadiene styrene can be found as a graft copolymer, in which styrene-acrylonitrile polymer is formed in a polymerization system in the presence of polybutadiene rubber latex; the final product is a complex mixture consisting of styrene-acrylonitrile copolymer, a graft polymer of styrene-acrylonitrile and polybutadiene and some unchanged polybutadiene rubber.
Where acrylonitrile are synthetic monomers produced from propylene and ammonia; butadiene is a petroleum hydrocarbon obtained from butane; and styrene monomers, derived from coal, are commercially obtained from benzene and ethylene from coal.

 Laminated plastic sheeting and containers made therefrom - Patent 3993810
An intermediate layer between the two exposed inner and outer layers of the container may be utilized comprising poly(acrylonitrile-butadiene-styrene) of reduced acrylonitrile content to permit bonding of both the outer and inner layer to the intermediate layer.
The outer layer is most preferably poly(acrylonitrile-butadiene-styrene) typically containing from about 20 to 40 percent by weight of acrylonitrile units, and desirably about 25 to 30 percent, to provide the container of this invention with an appropriate degree of oxygen and water vapor impermeability.
It can also be compatible with poly(acrylonitrile-butadiene-styrene) terpolymers which have more than 20 percent by weight of acrylonitrile units, as is preferably the case with respect to the outer layer of the containers of this invention, so that excellent bonding is also achieved in the interface between the outer layer and the intermediate layer.

 Acrylonitrile Butadiene Styrene (ABS) Plastic Resin
Acrylonitrile Butadiene Styrene (ABS) - This material is a terpolymer of acrylonitrile, butadiene and styrene.
Considerable variation is, of course, possible resulting in many different grades of acrylonitrile butadiene styrene with a wide range of features and applications.
Acrylonitrile butadiene styrene materials can be processed by any of the standard thermoplastic processing methods.

 Tangram Technology Ltd. - Polymer Data File - ABS
ABS (Acrylonitrile - butadiene - styrene terpolymer) is a member of the styrene family of polymers and shares many properties with the PS type of polymer.
The actual properties of a particular ABS material depend on the blend ratio of the three major constituents (Acrylonitrile, butadiene and styrene).
The material properties can be tailored to give specific desired properties: the acrylonitrile component gives chemical resistance and heat stability, the butadiene gives toughness and impact strength and the styrene gives rigidity and processability.

Any substance that in water solution tastes sour, changes the colour of certain indicators, promotes certain chemical reactions, etc. Examples of acids include inorganic substances such as sulfuric, nitric, and phosphoric acids, and organic compounds such as citric or maleic acid.
Acrylonitrile is a chemical intermediate used in acrylic fibres, ABS (acrylonitrile-butadiene-styrene), SAN (styrene-acrylonitrile) and NBR (nitrile-butadiene-rubber).
ABS is a tough, heat-resistant and impact-resistant thermoplastic, the acrylonitrile providing heat resistance, and the styrene units giving rigidity.

 plastics materials Acrylonitrile Butadiene Styrene ABS
ABS is readily modified both by the addition of additives and by variation of the ratio of the three monomers Acrylonitrile, Butadiene and Styrene: hence grades available include high and medium impact, high heat resistance, and electroplatable.
Styrene Acrylonitrile copolymers have been available since the 1940’s and while its increased toughness over styrene made it suitable for many applications, its limitations led to the introduction of a rubber (butadiene) as a third monomer and hence was born the range of materials popularly referred to as ABS plastics.
These became available in the 1950’s and the variability of these copolymers and ease of processing has led to ABS becoming the most popular of the engineering polymers.

Acrylonitrile Butadiene Styrene (ABS) is the polymerization of Acrylonitrile, Butadiene, and Styrene monomers.
Chemically, this thermoplastic family of plastics is called "terpolymers", in that they involve the combination of three different monomers to form a single material that draws from the properties of all three.
