Patent ID: 7112314

Claim:
A process for the polymerization of olefin monomer comprising: contacting organic acyl halide and peroxide complex in aprotic solvent to produce a diacyl peroxide solution comprising diacyl peroxide dissolved in said aprotic solvent, said aprotic solvent being compatible with the diacyl peroxide, organic acyl halide and peroxide complex and being substantially free of compounds oxidizable by the peroxide complex or by products of the reaction of organic acid halide with peroxide complex, said aprotic solvent being chosen to not interfere with said polymerization of said olefin monomer; limiting the amount of water present during said contacting so as to prevent formation of an aqueous phase; collecting said diacyl peroxide solution; and initiating polymerization of said olefin monomer with said diacyl peroxide contained in said diacyl peroxide solution, said diacyl peroxide solution being used directly in said polymerization of said olefin monomer.
