Abstract
Liquid, linear, crosslinkable phosphazene compositions and a process for their preparation are disclosed. These liquid compositions, prepared from normally solid polyphosphazene, contain the polyphosphazene in admixture with from about 1 to about 30 parts per hundred parts of polymer of a polythiol, a polyacrylate, a polymethacrylate or mixtures thereof such that the combination has a viscosity of less than 500,000 cps at 23.degree. C. These compositions are easily handled and can be crosslinked at ambient temperatures.
