Patent ID: 6858674

Claim:
A primary carbamate functional material of the formula: wherein X is a primary carbamate group, n is an integer of 2 or more, n′ is an integer of 1 or more, R 0 , R 1 , R 2 , R 3 , R 4 and R 5 are independently H, an alkyl group, an aromatic group, or mixtures thereof, at least one R 1 or R 2 group is not hydrogen, L is a linking group, j is a number equal to 1 or greater, P is a material selected from the group consisting of a compound, an oligomer, a polymer, and mixtures thereof, substantially all primary carbamate groups X are attached to carbon atoms having a lower degree of substitution than a carbon atom to which linking group L is attached, and the primary carbamate functional material comprises the reaction product of (1) at least one material P comprising one or more functional groups (i) which are reactive with a functional group Z but which are substantially nonreactive with a primary carbamate group X of monomeric reactive compound (2), (2) a monomeric reactive compound comprising one or more structures of the formula: wherein X is a primary carbamate group, Z is a functional group reactive with at least one functional group of material (1) and is selected from the group consisting of hydroxy groups, halide groups, and derivatives thereof, n is an integer of 2 or more, n′ is an integer of 1 or more, and R 0 , R 1 , R 2 , R 3 , R 4 and R 5 are independently H, an alkyl group, an aromatic group, or mixtures thereof, with the provisos that (i) at least one R 1 or R 2 group is not hydrogen, and (ii) in substantially all structures, primary carbamate group X is attached to a carbon atom having a lower degree of substitution than a carbon atom to which functional group Z is attached.
