Abstract: A biocompatibilizing process in which a substrate having a surface which bears substrate pendant functional groups is biocompatibilized by coating it with a coating composition containing a polymer formed from a radical polymerizable monomers including a radical polymerisable zwitterionic monomer and a radical polymerizable monomer containing a reactive group to form a polymer having zwitterionic groups and pendant reactive groups and the said pendant reactive groups are reacted to form covalent bonds with said substrate pendant functional group and thereby form a stable coating of polymer on the said surface.

Abstract: A crosslinkable composition is provided including copolymer particles having phosphorus acid groups dispersed in an aqueous medium, and polycarbodiimide, wherein the crosslinkable composition is substantially free of water soluble phosphorus acid compounds. Also provided is a process for forming the crosslinkable composition and a method for crosslinking the crosslinkable composition. The crosslinkable composition is useful as a coating composition to prepare coatings for various substrates including metal, wood, glass, paper, and leather.

Abstract: Process for the preparation of a derivative of a polymer having at least one functional group, characterized in that the process comprises the following step (i): (i) reaction of the polymer having at least one functional group, with at least one activating reagent or at least one derivative of an activating reagent in homogeneous phase.

Abstract: A composition that includes a fluorine-containing copolymer containing at least 30 mol % of residues having the following alternating structural unit: —[DM—AM]— where DM represents a residue from a donor monomer having the following structure (I): where R1 is linear or branched C1 to C4 alkyl; R2 is selected from methyl, linear, cyclic or branched C1 to C20 alkyl, alkenyl, aryl, alkaryl and aralkyl; and AM represents an acceptor monomer. The copolymer contains at least 5 wt. % fluorine. The composition may include co-reactive functional groups and may be a thermosetting composition, which can be used to coat a substrate. The thermosetting composition may be part of a multi-component composite coating composition that includes a base coat deposited from a pigmented film-forming composition and a substantially pigment free top coat applied over at least a portion of the base coat.

Abstract: The invention provides a method for preparing a 1-benzotriazolylcarbonate ester of a water-soluble and non-peptidic polymer by reacting a terminal hydroxyl group of a water-soluble and non-peptidic polymer with di(1-benzotriazolyl)carbonate in the presence of an amine base and an organic solvent. The polymer backbone can be poly(ethylene glycol). The 1-benzotriazolylcarbonate ester can then be reacted directly with a biologically active agent to form a biologically active polymer conjugate or reacted with an amino acid, such as lysine, to form an amino acid derivative.

Abstract: Cross-linked electrically conductive polymers, in particular electrically conductive, polyaniline are described. Dopants and substituents having pendant cross-linkable functionality are used which form a cross-linked conducting polymer network. The cross-linking functionality can be hydrogen-bonding as well as chemically polymerizable or cross-linkable. A conjugated path between chains can also be incorporated. The resulting cross-linked conducting polymers have enhanced thermal and environmental stability. The dopant cannot readily be washed out with solvents or diffuse out upon exposure to heat. In addition, the cross-linked polymers have enhanced electrical conductivity.
