Abstract
This invention relates to a method of curing unsaturated polyester resins or mixtures of such resins and a monomer copolymerizable therewith. More particularly, the invention relates to the curing of such resins and mixtures thereof with a composition comprising acetylacetone peroxide (AAP) in an amount of from about 30 to about 35 percent and a high temperature peroxide. Preferably, the high temperature peroxide is t-butyl peroxybenzoate (TBPB) and is present in an amount of from about 5 to about 10 percent of the composition.
