THERMOFORMABLE, THERMOSETTABLE EPOXY/POLYESTER REACTION PRODUCTS |
摘要 |
Thermoformable, thermosettable resins essentially free of secondary alcohol groups are obtained by reaction of oxiranes in active hydrogen-free epoxies with carboxylate or carbonate groups in active hydrogen-free aryl polyesters, polycarbonates or copolyestercarbonates in the presence of catalytically effective amounts of certain polyorgano phosphonium or phosphine imminium salts.
