Sulfone-ester polymers containing pendent ethynyl groups

摘要: Sulfone-ester polymers containing pendent ethynyl groups and a direct multi-step process for preparing same are disclosed. The involves the conversion of bromo group to while route reacting hydroxy-terminated sulfone oligomer or with stoichiometric amount 5-(4-ethynylphenoxy)isophthaloyl chloride. chloride also
