	Polymer - Wikipedia, the free encyclopedia
		The intermolecular forces in polymers are determined by dipoles in the monomer units.
		Polymers containing amide groups can form hydrogen bonds between adjacent chains; the positive hydrogen atoms in N-H groups of one chain are strongly attracted to the oxygen atoms in C=O groups on another.
		Polymer known as polymer substrate is used for everyday banknotes in Australia and New Zealand, and is also used in commemorative notes in other countries.

	Patent 6,011,082 (Site not responding. Last check: 2007-11-07)
		Polymer substrates having the surface modification of the present invention are capable of having a surface modification agent, such as heparin, adhere to the surface of the polymer substrate.
		The surface of the polymer is modified by a surface interpenetrating polymer network, which provides for the indirect bonding of the polymer network with the surface of the polymer substrate in a caternary connection or other form of chain entanglement.
		On the surface of the polymer, however, the polymerization results in an interpenetrating polymer network due to the presence of the swelling monomer, which polymerizes together with the functional monomer at the surface interface of the polymer substrate.

	Patent 4339498: Heat sealable packaging film comprising propylene polymer substrate and a surface layer blend of olefin ...
		Multiple-layer, heat-sealable films are described comprising a substrate layer of polypropylene homopolymer or copolymer, or blends thereof with compatible polyolefins; and at least one heat-sealable surface layer of an interpolymer of propylene and two different higher alpha-olefins; a copolymer of butene-1 and a higher alpha-olefin or an interpolymer of ethylene, propylene and a higher olefin.
		With the two-layer films of this invention containing a proportion of the surface layer polymer in the substrate layer it is possible to obtain a useful degree of sealability of the substrate layer to itself where the flap meets the top and bottom of the bag.
		The strength of this seal between substrate surfaces is not nearly as strong as the strength of the seal between the surface layers, but is sufficient to adhere the flap to the top and bottom edges of the bag.

		In the preferred embodiments the first polymer is an ionically conductive polymer, the monomers of which have a hetero atom with a lone pair of electrons available for the metal ions of a metal salt to attach to and move between during conduction, when the first polymer is mixed with a metal salt.
		In certain embodiments the inactive polymer substrate is a metallized polymer substrate having a thin metallization layer which serves as the adherent electrically conductive layer.
		The polymer substrate layer ranges in thickness from 0.5 micron to greater than 50 microns, thereby rendering it very flexible for ease of coating and handling, to avoid kinking and deformation thereof, during manufacture of lithium polymer electrolyte batteries.

	RBA: Conference Paper-Polymer Notes and the Meaning of Life
		Because polymer substrate is more expensive than paper substrate, but by a factor considerably less than the increase in durability, a move to polymer substrate involves the note issuer in an initial greater outlay.
		Polymer substrate offers the potential for significant ongoing innovation, improved quality of features, improved durability of security features relative to the life of the note, and the incorporation of different technologies that make counterfeiting using just print or traditional add-on features less likely.
		Even if countries decide not to use polymer substrate they probably will have already benefited from polymer because it is only as a consequence of polymer that traditional suppliers are now producing long-life papers, through the use of coatings or new fibres, and new security features.

	Patent 4364731: Methods for producing adhesive bonds between substrate and polymer employing an intermediate oxide
		In the case of sputter deposition, stress in the deposit is minimized by controlling the temperature of the substrate and by biasing the substrate during deposition.
		The polymeric materials whose adhesion to the substrate is improved by the methods of this invention include, for example, epoxy-resins, urethane resins, vinyl esters, rubber latex, and acrylic resins.
		For example, for some polymer substrates it may be highly desirable to sputter etch the substrate in oxygen or argon/oxygen prior to sputter depositions of the oxide.

	National Synchrotron Light Source
		The ability to adjust the interactions between a material or a molecule and a substrate is desirable for a number of applications.
		In polymer blends, differences in interfacial energies, which reflect a preferential interaction, generally cause one polymer to segregate to the substrate or air interface.
		Both polymers exhibit comparable glass transition temperatures (temperatures below which a polymer becomes hard and brittle) of approximately102 to 120 degrees Celsius (°C) and are readily codissolved in a common solvent.

	Introduction
		Spin casting of polymers is a simple technique, which is widely used for producing very thin organic films by applying centrifugal force, linear shear stress, and uniform evaporation of a polymer solution on a rotating disk or a substrate [Meyerhofer, 1978; Hall et al., 1998].
		In the spin casting process, a solution of polymer is first deposited on the substrate, and the substrate is then accelerated rapidly to the desired rotation rate.
		The vertical displacement of the polymer surface is the same as the uniform model, expect in the nonuniform mass diffusion region.

		When a polymer solution is exposed to a surface, segments of a polymer chain can be adsorbed in one of three conformations: (1) trains; (2) loops; and (3) tails.
		The vinyl polymers being studied have pendant groups, which vary in size and/or polarity, and inorganic supports such as silica or alumina typically have hydroxyl groups on their surfaces.
		Furthermore, the polymer is typically deuterated at only one site, limiting the information available about the relative strengths of the interactions between different parts of the polymer (backbone vs. pendant groups) and the substrate.
