Abstract

Multifunctional cyclobutarene peroxide polymerization initiators comprising at least one cyclobutarene moiety linked through the aromatic ring to at least one peroxide containing group which catalyze free radical polymerizations, as well as participate in cyclobutarene initiated ring opening polymerizations. The cyclobutarene peroxides of this invention are useful for the production of cross-linked, branched and graft polymeric compositions.
