SOLID POLYAMINOESTER POLYMERS AND THEIR PRODUCTION

摘要

Solid polyaminoester polymers containing units of acrylic acid ester monomer having an average acrylate functionality of at lest 2.5 and of aliphatic amine monomer having a number average molecular weight of at most 1000, an average amine hydrogen functionality of at least 3 and an amine hydrogen equivalent weight of less than about 100, the equivalent ratio of acrylate to amine hydrogen being 0.5 to 2.0 in order to provide new polymers useful as thermoset plastics and moldable by reaction injection molding or liquid injection molding processes.
They may be prepared by introducing a monomer mixture containing the acrylate monomer and the amine monomer into a mold and allowing the mixture to react.
