ABSTRACT:
Compounds useful as crosslinking agents have the formula: ##STR1## wherein R.sub.1, R.sub.2, and R.sub.3 and R.sub.4 are independently vinyl, allyl, methallyl, propargyl, crotyl, C.sub.1 to C.sub.18 alkyl, aryl or inert group substituted derivatives thereof and where X is a saturated or unsaturated alkylene moiety having up to 12 carbon atoms saturated or unsaturated C.sub.1 -C.sub.18 heteroaliphatic, C.sub.5 -C.sub.18 heteroaromatic, C.sub.5 -C.sub.18 alicyclic or C.sub.1 -C.sub.18 heterocyclic, where n and m are independently 0 or integers of from 1-12 inclusive. These compounds are particularly useful as crosslinking agents for high temperature processable (>200.degree.) polymers, especially fluorocarbon polymers. Also described are polymer compositions comprising from about 0.1 weight percent to about 50 weight percent of said crosslinking agent or mixture of said crosslinking agents. The products resulting from melt fabrication and subsequent crosslinking of such compositions are useful as shaped articles, e.g., wire products. Most of said compounds are novel compositions of matter.
