CA 2629859

Trivalent organic phosphorus compounds are used in combination with tertiary aromatic amine cure promoters in connection with peroxide initiated curing of curable unsaturated resins such as cross-linkable polyesters. The curing is conducted in the presence or absence of monomers having a terminal double bond. Curing rates have been improved by use of such combinations.

L~invention concerne des composés organiques trivalents de phosphore utilisés en mélange avec des promoteurs de durcissement à base d'amine aromatique tertiaire pour un durcissement initié par des peroxydes de résines insaturées durcissables telles que des polyesters réticulables. Le durcissement est réalisé en présence ou en l~absence de monomères ayant une double liaison terminale. L~utilisation de tels mélanges permet d~améliorer les vitesses de durcissement.
