    摘要: The novel polyfunctional peroxides are compounds represented by the following general formula (1):R.sup.1 --CX.sub.3 (1)wherein R.sup.1 represents a linear alkyl group having 1 to 3 carbon atoms; and X represents a group: ##STR1## (wherein R.sup.2 represents a linear or branched alkyl group having 1 to 5 carbon atoms).Such polyfunctional peroxides include 1,1,1-tris(t-butylperoxycarbonyloxymethyl)propane and the like. The polymerization initiators for vinyl monomers comprise such polyfunctional peroxides. In the process for polymerizing vinyl monomers, a vinyl monomer is polymerized employing such polyfunctional peroxide at 60 to 160.degree. C.
