Claim Text:
1. A copolymer of Formula 1: wherein: a, c, d, and e are molar ratios varying between about 0.01 and about 0.90; b is a molar ratio varying between about 0 and about 0.90; A1 represents monomer units A, wherein monomer units A comprise a cyano-containing pendant group in which the cyano is not directly attached to the backbone of the copolymer; A2 represents monomer units A or monomer units B, wherein monomer units B comprise a film-forming pendant group; A3 represents monomer units C, wherein monomer units C comprise a poly(ethylene glycol), poly(propylene glycol) and/or poly(ethylene glycol ran propylene glycol) containing side chain terminated by a substituent comprising a cyano group, said side chain being attached to the backbone of the copolymer via an amide, a carbamate, an ester or a urea linker; A4 represents monomer units B; and A5 represents monomer units D, wherein monomer units D comprise at least one functional group capable of undergoing a crosslinking reaction via cationic polymerization, wherein monomer units A in A1 and A2 are different from each other and wherein monomer units B in A2 and A4 are different from each other; wherein each of the structural groups A1 through A5 are different from one another; wherein monomer units A are of formula: wherein: R is hydrogen, methyl or ethyl; R U V W is —CN or wherein monomer units B are of formula: wherein R is hydrogen, methyl or ethyl; U Z is alkyl or aryl, the alkyl being optionally substituted with one or more hydroxyl, alkyloxy or halide, and the aryl being optionally substituted with one or more alkyls that are optionally substituted with one or more hydroxyl, alkyloxy or halide; or wherein monomer units B are of formula: wherein R is hydrogen, methyl or ethyl; R U V A is —COOH, —PO(OH) wherein monomer units C are of formula: wherein: R is hydrogen, methyl or ethyl; J represents an amide, ester, carbamate or urea linker; and K and L together form said side chain, K comprising a poly(ethylene glycol), poly(propylene glycol) and/or poly(ethylene glycol ran propylene glycol) chain; and L being —CN or wherein R V wherein monomer units D are of formula: wherein: R is hydrogen, methyl or ethyl; E is absent or represents an amide or ester linker; F is alkyl optionally comprising one or more ether, ester, amine, amide, urea, piperazinyl, or carbamate functional group; or a poly(ethylene glycol), poly(propylene glycol) and/or poly(ethylene glycol ran propylene glycol) chain, the chain optionally having attached at either or both ends an alkyl optionally comprising one or more ether, ester, amine, amide, urea, piperazinyl, or carbamate functional group; and G is the functional group capable of undergoing a crosslinking reaction via cationic polymerization.
