ABSTRACT:
Compositions 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 ii) a reaction product of the primary carbamate material and an extending agent, and c) optionally, a chain extension agent that has at least difunctional reactivity with an isocyanate. Also, methods of making these compositions.
