Abstract

A method for radical cross-linking or organic polymers, is disclosed which uses a cross-linking enhancer of the following formula ##STR1## wherein R is alkenyl or alkynyl; PA1 R.sup.1 is alkylene, alkenylene, alkynylene or --(R.sup.2 --O).sub.m --R.sup.2 --, R.sup.2 is CH.sub.2, (CH.sub.2).sub.2, (CH.sub.2).sub.3 or CH.sub.2 --CH(CH.sub.3), and m is 1 to 50; and n is 1 to 10.
