Abstract

Dialkyl alkylenebis(peroxydicarbonates) and oxyalkylenebis(peroxydicarbonates) and corresponding higher polyfunctional peroxydicarbonic acid esters are useful initiators of vinyl polymerization. These compounds are prepared by reacting a sodium alkylperoxycarbonate with a diol bis(chloroformate) at from about -10.degree.C to about 20.degree.C.
