我们已经开发了一系列合成的可生物降解的聚合物,这些聚合物由人体代谢内源性的结构单元组成,被称为聚(多元醇二十二酸)(PPS)聚合物。通过改变聚苯硫醚多元醇单体的种类和反应组成比,可以调节聚苯硫醚聚合物的性能。这些热固性网络的拉伸杨氏模数为0.37±0.08~378±33 Mpa,最大断裂伸长率为10.90±1.37~205.16±55.76%,玻璃化转变温度为~7~46°C。聚苯硫醚聚合物在体内外的生物相容性与L-乳酸-乙醇酸共聚物(PLGA)相似。
We have developed a family of synthetic biodegradable polymers that are composed of structural units endogenous to the human metabolism, designated poly(polyol sebacates) (PPS) polymers. Material properties of PPS polymers can be tuned by altering the polyol monomer and reacting stiochiometric ratio of sebacic acid. These thermoset networks exhibited tensile Young’s moduli ranging from 0.37 ± 0.08 to 378 ± 33 MPa with maximum elongations at break from 10.90 ± 1.37 to 205.16 ± 55.76%, and glass-transition temperatures ranged from ~7 to 46 °C. In vitro degradation under physiological conditions was slower than in vivo degradation rates observed for some PPS polymers. PPS polymers demonstrated similar in vitro and in vivo biocompatibility compared to poly(L-lactic-co-glycolic acid) (PLGA).
