Abstract

Optionally nucleo-substituted styrene polymers are crosslinked at temperatures above 110.degree. C. with combinations of crosslinkage promoters containing at least two polymerizable C--C double or C--C triple bonds in the molecule, and organic peroxides (with the exception of hydroperoxides, peracids, and ketone peroxides) having a 10 hour halflife temperature below 106.degree. C.
