Phosphonitrilic polymers with curability by sulfur accelerated cures or radiation cures

摘要

Improvements in phosphonitrilic polymers and compositions based on the same, possessing outstanding low temperature flexibility and good physical strength over a broad range of service conditions, are obtained by the incorporation of some unsaturated substituents in the side chains on the -P=N- backbone, to adapt the polymers to vulcanization with sulfur accelerated cure systems or radiation cure.
