Patent ID: 6844395

Claim:
A composition comprising a reaction product of a. an asymmetrical, saturated polyisocyanate that is non-cyclic, non-aromatic, and has at least 3 carbon atoms in the polyisocyanate per isocyanate group, b. a material that is at least one of i. a primary carbamate material having at least one functional group reactive with an isocyanate and at least one primary carbamate group or a group convertible to a primary carbamate group, and/or ii. a reaction product of the primary carbamate material and an extending agent, wherein the primary carbamate material is represented by the following structure: wherein R 1 , R 2 , R 3 , R 4 , R 5 , and R 6 are each independently H or C 1 -C 6 alkyl, and n is 0 or a positive integer, and c. optionally, a chain extension agent that has at least difunctional reactivity with an isocyanate.
