Abstract

The interaction of phenylphosphonic dichloride and sodium or lithium phosphate gives glassy polymers which are hybrids of lithium and sodium metaphosphate glasses and polyphenylphosphonates. Tg's increases as the proportion of the alkali metal incorporated in the polymer increases. Reaction is most conveniently carried out by heating in chloroform under reflux. Polymers were prepared with up to 1 in 5 of the phosphorus atoms associated with Li^+^ and up to 1 in 6 associated with Na^+^. Glasses could also be formed by reaction in the absence of solvent but difficulty was experienced in the complete removal of hydrogen chloride.
