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.

Phenol formaldehyde resole is made by a low catalyst level process which eliminates the need to isolate the resin from the reaction mixture. The resole is blended with a vinyl pyridine latex and a resorcinol based curing agent and is used as a cord dip. The vinyl pyridine latex may be a latex blend. The dipped cord is used as reinforcement in rubber tires.
