Phosphinic acids of the formula ##STR1## wherein (A) R is ##STR2## (1) X is 3-phenylene or 4-phenylene, and (2) Y is a direct bond, ##STR3## (B) R' is R, lower alkyl of from 1 to 3 carbon atoms, 4-biphenylyl, or phenyl. These acids are neutralized with an equivalent amount of alkali metal carbonates to form alkali metal salts which react with ZnCl.sub.2 to form polymers having high thermal stability.
公式为 ##STR1## 的膦酸,其中 (A) R 为 ##STR2## (1) X 为 3-苯基或 4-苯基,且 (2) Y 为直接键,##STR3## (B) R' 为 R、1至3个碳原子的低级烷基、4-联苯基或苯基。这些酸用等量的碱金属碳酸盐中和形成碱金属盐,然后与 ZnCl.sub.2 反应形成高热稳定性聚合物。
