MODIFICATION OF (CO)POLYMERS WITH CYCLIC KETONE PEROXIDES.

摘要

A process for the modification of (co)polymers employing an organic peroxide comprising the step of contacting a (co)polymer with organic peroxide under conditions whereby at least some of said organic peroxide is decomposed, is disclosed. The process is characterized in that at least 20 percent of the total active oxygen content of said organic peroxide is attributable to one or more cyclic ketone peroxides. In a second aspect, the invention relates to the use of an organic peroxide composition wherein at least 20 percent of the total active oxygen content is contributed by one or more cyllic ketone peroxide(s) modify (co)polymers. It has been found that these cyclic ketone peroxides are extremely efficient in (co)polymer modification processes.
