Abstract:
1. 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 at least one R 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 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 with the provisos that (i) at least one R (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.
