摘要： Resinous compositions are prepared by the reaction of a composition comprising cyclic polycarbonate oligomers with at least one polyepoxide compound, in the presence of a polycarbonate formation catalyst. The cyclic polycarbonate oligomer composition is preferably a mixture of oligomers of varying degrees of polymerization, and the polyepoxy compound is preferably triglycidyl isocyanurate or a bis-epoxy-terminated bisphenol A-epichlorohydrin concentrate. There may also be present a polycarbonate crosslinking agent. The product of the reaction is a crosslinked polycarbonate network. The method is particularly useful in reactive processing operations such as reaction injection molding.
