Abstract
Novel peroxyketals having the general formula ##STR1## are provided, wherein R.sup.1 represents a tert. alkyl group having 4-12 carbon atoms and R.sup.2 represents a branched or a non-branched alkyl group having 1-12 carbon atoms or a substituted or unsubstituted cycloalkyl group having 5-12 carbon atoms. The peroxyketals can be used to advantage for initiating the copolymerization reaction of ethylenically unsaturated compounds such as unsaturated polyester resins containing both an unsaturated polyester and an ethylenically unsaturated monomer such as styrene.
