Abstract
Acyl peroxycarbonic esters of the formula ##STR1## in which R is methyl or ethyl, R' is alkyl, and R and R' together have 17 or more carbon atoms. The compounds have unusual thermal stability, together with improved polymerization initiating efficiency. Particularly outstanding efficiency is found in connection with the polymerization of methyl methacrylate.
Claims8
Acyl peroxycarbonic esters of the formula:
- ##STR4## where R is selected from methyl and ethyl;
- and R' is an alkyl group which together with R contains a total of 17 to about 25 carbon atoms.
