摘要:
A potassium catalyst is used in combination with a cobalt catalyst to increase the reaction rate and/or reduce the reaction temperature of a melt polymerization process for producing an anisotropic melt-phase forming polymer derived from p-hydroxybenzoic acid, 6-hydroxy-2-naphthoic acid, aromatic hydroxycarboxylic acid, aromatic diol, at least a portion of which is resorcinol and at least one aromatic dicarboxylic acid, compared to a like process wherein either catalyst is used alone.
摘要(中):
钾催化剂与钴催化剂结合使用以提高反应速率和/或降低用于制备衍生自对羟基苯甲酸6-羟基-2-甲基丙酸的各向异性熔融相形成聚合物的熔融聚合方法的反应温度, 萘酚酸,芳族羟基羧酸,芳族二醇,其中至少一部分是间苯二酚和至少一种芳族二羧酸,与其中任一种催化剂单独使用的类似方法相比。
