CYCLIC KETONE PEROXIDES AS POLYMER INITIATORS

摘要

A 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 formulae (I-III). These cyclic ketone peroxides are highly efficient as polymerization initiators. Also new cyclic ketone peroxides and compositions comprising such compounds are provided.
