    摘要: Disclosed are heat-curable polymer compositions comprising a resin of ethylenically unsaturated polyester or vinyl ester, an organic peroxide initiator component, a promoter for decomposition of said peroxide, and an inhibitor of polymerization of the resin, wherein the inhibitor is present in an amount with respect to the amount of promoter present such that the gel time of the composition is independent of the amount of promoter present. Observance of the indicated ratio between promoter and inhibitor provides the advantages of both components and also enables the operator to obtain curing performance and characteristics as a function solely of the peroxide content of the composition.
