Abstract

Procedure for the preparation of unsaturated polyester resins, initially dissolved in copolymerizable ethylenically unsaturated monomers, which harden with cobalt compounds and hydroperoxides with short gel times and accelerated hardening, characterized in that at room temperature, the resin of unsaturated polyester, a promoter system consisting of a combination of 0.01-1% by weight, preferably 0.02-0.3% by weight, of a cyclopentanone derivative of the general formula. ** (See formula) ** where X is an acyl, carbonamide, nitrile, or carboxylic acid ester group, and 0.01-0.1% by weight, preferably 0.02-0.06%, of a tertiary amine of the general formula. ** (See formula) ** where Z means an optionally substituted aryl group and Y respectively Y'means an alkyl group or an alkanol group.
