Abstract
Peroxy-terminated polycarbonates are prepared by the reaction of an aromatic dihydroxy compound, preferably a bisphenol, with phosgene in one or two steps, in the presence of a peroxy ester such as the mono-t-butyl perester of maleic acid. The peroxy-terminated polycarbonates may be employed to initiate vinyl polymerization of ethylenically unsaturated monomers or to react with polymers containing ethylenically unsaturated groups, to form copolymers which are useful as compatibilizers for blends of polycarbonates with said polymers.
