ABSTRACT:
Unsaturated oligomers and solutions thereof are stabilized with a trisubstituted urea to provide improved storage stability. The stabilized unsaturated oligomer solutions are useful in lactam polymerization processes which yield nylon block copolymers containing unsaturated oligomer segments. The unsaturated oligomers disclosed herein have at least 4 carbons and have pendant thereto at least one hydroxy, amine, epoxy, acyllactam, or acyllactam precursor group.
