ABSTRACT:
This invention provides compositions containing thermally stable prepolymers with azadiene end groups, and compositions containing such prepolymers in combination with dienophiles and the chain-extended and cross-linked polymers obtained from these systems.
The combination of such prepolymers with dienophiles facilitates processing of the prepolymer resin by lowering the softening and curing temperatures under processing conditions.
