摘要 主要研究了丙交酯在双金属氧桥催化剂作用下的开环本体聚合,探讨了聚合反应温度,催化剂用量,及体系真空度对聚丙交酯的分子量的影响,并初步测定了聚丙交酯的降解速度。 The ring -opening polymerization of DL-lactide by bimetallic μ-oxoalkoxide catalyst were studied. The polymerization of temperature, catalyst quantity and degree of vacuum in system effected on molecalar weight of polylactide were disscussed.
