Abstract
A polyperoxyketal having at least one carboxy group--an acid, hydrocarbon ester, a metal ion, or as part of an anhydride. Illustrations are: n-Butyl .gamma.,.gamma.-bis-(t-butylperoxy) valerate and Barium .gamma.,.gamma.-bis(t-butylperoxy) valerate. These polyperoxyketals are vulcanizing agents for thermoplastic polymers such as rubber and ethylenepropylene rubber.
