Abstract
A process for the preparation of a curable molding or coating compound containing an unsaturated polyester resin is disclosed. The process comprises substantially uniformly incorporating into said resin effective amounts of a cerium promoter and a catalytically active tertiary butyl peroxy ester or a tertiary amyl peroxy ester of a non-.alpha.-branched aliphatic or aromatic, mono- or dicarboxylic acid.

A process for the preparation of a curable molding or coating compound containing an unsaturated polyester resin consisting essentially of substantially uniformly incorporating into said resin effective amounts of a cerium promoter and a catalytically active peroxy ester selected from the group consisting of tertiary butyl peroxy esters of non-.alpha.-branched aliphatic monocarboxylic acids, tertiary butyl peroxy esters of non-.alpha.-branched aromatic monocarboxylic acids, tertiary butyl peroxy esters of non-.alpha.-branched aliphatic dicarboxylic acids, tertiary butyl peroxy esters of non-.alpha.-branched aromatic dicarboxylic acids, tertiary amyl peroxy esters of non-.alpha.-branched aliphatic monocarboxylic acids, tertiary amyl peroxy esters of non-.alpha.-branched aromatic monocarboxylic acids, tertiary amyl peroxy esters of non-.alpha.-branched aliphatic dicarboxylic acids, and tertiary amyl peroxy esters of non-.alpha.-branched aromatic dicarboxylic acids.
A curable molding or coating compound consisting essentially of an unsaturated polyester resin having substantially uniformly incorporated therein effective amounts of a cerium promoter and a catalytically active peroxy ester selected from the group consisting of tertiary butyl peroxy esters of non-.alpha.-branched aliphatic monocarboxylic acids, tertiary butyl peroxy esters of non-.alpha.-branched aromatic monocarboxylic acids, tertiary butyl peroxy esters of non-.alpha.-branched aliphatic dicarboxylic acids, tertiary butyl peroxy esters of non-.alpha.-branched aromatic dicarboxylic acids, tertiary amyl peroxy esters of non-.alpha.-branched aliphatic monocarboxylic acids, tertiary amyl peroxy esters of non-.alpha.-branched aromatic moncarboxylic acids, tertiary amyl peroxy esters of non-.alpha.-branched aliphatic dicarboxylic acids, and tertiary amyl peroxy esters of non-.alpha.-branched aromatic dicarboxylic acids, and tertiary amyl peroxy esters of non-.alpha.-branched aromatic dicarboxylic acids.
A process for curing an unsaturated polyester consisting essentially of compressing and heating said resin to a temperature effective to cure the polyester, in the presence of effective amounts of a cerium promoter and a catalytically active peroxy ester selected from the group consisting of tertiary butyl peroxy esters of non-.alpha.-branched aliphatic monocarboxylic acids, tertiary butyl peroxy esters of non-.alpha.-branched aromatic monocarboxylic acids, tertiary butyl peroxy esters of non-.alpha.-branched aliphatic dicarboxylic acids, tertiary butyl peroxy esters of non-.alpha.-branched aromatic dicarboxylic acids, tertiary amyl peroxy esters of non-.alpha.-branched aliphatic monocarboxylic acids, tertiary amyl peroxy esters of non-.alpha.-branched aromatic monocarboxylic acids, tertiary amyl peroxy esters of non-.alpha.-branched aliphatic dicarboxylic acids, and tertiary amyl peroxy esters of non-.alpha.-branched aromatic dicarboxylic acids.
