Zusammenfassung:PCT No. PCT/EP95/02829 Sec. 371 Date Mar. 13, 1997 Sec. 102(e) Date Mar. 13, 1997 PCT Filed Jul. 14, 1995 PCT Pub. No. WO96/03444 PCT Pub. Date Feb. 8, 1996A 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 the said organic peroxide is decomposed, is disclosed. The process is characterized in that at least 20% 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% of the total active oxygen content is contributed by one or more cyclic ketone peroxide(s) modify (co) polymers. It has been found that these cyclic ketone peroxides are extremely efficient in (co) polymer modification processes.
