摘要
以癸二酸和二聚酸预聚物为单体 ,采用高真空熔融缩聚法 ,得到较高相对分子质量的聚 (二聚酸 癸二酸 )共聚物 .合成的聚合物分别用FT IR ,GPC ,DSC和TGA等进行了表征 。
Poly (dimmer acid sebacic acid) copolymers with high molecular weights are successfully prepared by melting condensation of dimmer acid prepolymer and sebacic acid prepolymer under high vacuum conditions. The copolymers are characterized by FT IR, GPC, DSC, and TGA analyses. In vitro degradation of the copolymers in phosphate buffer at 37?℃ are determined. The release profiles of model drug, ciprofloxcin hydrochloride, from the copolymers follow first order release kinetics.
