PCT No. PCT/EP96/01012 Sec. 371 Date Feb. 27, 1998 Sec. 102(e) Date Feb. 27, 1998 PCT Filed Mar. 6, 1996 PCT Pub. No. WO96/27620 PCT Pub. Date Sep. 12, 1996A process for the preparation of (co)polymers employing a peroxide composition comprising at least one organic peroxide wherein at least 20% of the total active oxygen content of said organic peroxide is attributable to one or more cyclic ketone peroxides represented by the following formulas I-III: These cyclic ketone peroxides are highly efficient as polymerization initiators. Also new cyclic ketone peroxides and compositions comprising such compounds are provided,
