Abstract:
1. A thermoset elastomer comprising the reaction product of (a) an ambient temperature liquid epoxy-terminated prepolymer formed by reacting a polyoxyalkyleneamine having a molecular weight of from 3,000 to 20,000 with an excess of epoxide, wherein the polyoxyalkyleneamine is represented by the formula: wherein R is the nucleus of an oxyalkylation-susceptible initiator containing 2-12 carbon atoms and 2 to 8 active hydrogen groups, U is an alkyl group containing 1-4 carbon atoms, T and V are independently hydrogen or U, n is number selected to provide a polyol having a molecular weight of 2,900 to 29,500 and m is an integer of 3 to 8 corresponding to the number of active hydrogen and (b) a curing agent comprising at least one amine or polyamine having an equivalent weight of less than 200 and having 2 to 5 active hydrogen atoms.
