ABSTRACT:
A polymeric peroxy ester, which consists of a structural unit represented by the formula (I): ##STR1## and a structural unit represented by the general formula (II): ##STR2## wherein R represents --CH.sub.2 CH.sub.2 --, --C.tbd.C-- or ##STR3## and had an average molecular weight or 1,000-15,000, said structural units (I) and (II) being bonded alternately in a molar ratio within the range of from 6:4 to 4:6, has a 10-hour half-life period temperature of 70.degree.-85.degree. C. and a high activity at relatively high temperature, is safe in the production and handling, is adapted to be used as a polymerization initiator in the polymerization of vinyl monomer, and can produce a vinyl polymer having a high molecular weight.
