  There are provided novel homopolyanhdyrides of carboxyaryloxyalkanoic acids, e.g. p-carboxyphenoxyacetic acid or 6-(p-carboxyphenoxy)hexanoic acid, capable of being formed into shaped articles. The homopolyanhydrides may be prepared by heating under reflux a solution of the acid monomer in acetic anhydride to form a mixed anhydride of the acid monomer and acetic acid and melt polycondensing the prepolymer by heating it under vacuum in an inert atmosphere. Due to their property of hydrolytic cleavage at predictable rates, the homopolyanhydrides are suitable as polymer matrices providing for the controlled release of an agent such as a drug.

  本发明提供了新型的羧基芳氧基烷酸均聚氰基酸酐，例如对羧基苯氧基乙酸或 6-(对羧基苯氧基)己酸，可制成成型物品。均聚酸酐的制备方法是：在回流条件下加热酸单体在乙酸酐中的溶液，形成酸单体和乙酸的混合酸酐，然后在惰性气氛中真空加热预聚物，使其熔融缩聚。由于均聚酸酐具有以可预测的速度水解裂解的特性，因此适合用作聚合物基质，用于控制药物等制剂的释放。
