摘要

A thermosetting, free radical curable unsaturated polymer resin composition and a method of curing thermosetting, free radical curable, unsaturated polymer resin compositions having a pH greater than 4.5 measured as a 10 weight percent methanol solution and containing a tertiary amine as an esterification catalyst and/or an accelerator, such resin being admixed with a copolymerizable monomer, wherein a curing system of a ketone peroxide and a redox active metal salt is employed. An effective amount of an organic sulfonic acid is added to the resin prior to curing, whereby by gas generation upon curing is reduced.
