A composition comprising components A, B and optionally C, wherein component A comprises at least one carboxy-terminated polyarylate or an otherwise functionalized polyarylate. Component B is an organic species which can react with the reactive endgroups of component A, and component C is a catalyst or mixture of catalysts. The carboxy-terminated and functionalized polyarylates may be prepared by a solution polymerization method wherein a stoichiometric excess of a diacid chloride is reacted with a dihydroxy-substituted aromatic compound (e.g. resorcinol) in the presence of an organic base to provide an intermediate chlorocarbonyl group-substituted polyarylate which chlorocarbonyl groups may be elaborated to a variety of reactive endgroups including carboxy groups and epoxy groups.
一种由组分 A、B 和可选的 C 组成的组合物,其中组分 A 包括至少一种羧基封端的聚芳酸酯或以其他方式官能化的聚芳酸酯。成分 B 是一种有机物,可与成分 A 的反应性端基发生反应,成分 C 是一种催化剂或催化剂混合物。羧基封端和官能化的聚芳基酸酯可通过溶液聚合法制备,该方法是在有机碱的存在下,将一定量过量的二酰
氯与二羟基取代的芳香族化合物(如
间苯二酚)反应,以提供一种中间
氯羰基取代的聚芳基酸酯,其中的
氯羰基可被细化为各种反应性端基,包括羧基和环氧基。
