采用微波辅助开环聚合法制备了聚碳酸三亚甲基（PTMC）。在没有任何金属化合物催化剂的情况下，以乙二醇（EG）为引发剂在单模微波炉中进行聚合。研究了反应混合物在不同功率和EG浓度下的温度-时间分布。微波法转化得到的PTMC和TMC单体的摩尔质量均高于常规方法。用差示扫描量热法研究了所得聚合物的热性能。微波辐照是制备PTMC的有效方法。(C) 2007 Elsevier Ltd.版权所有。
Poly(trimethylene carbonate) (PTMC) was synthesized successfully by microwave-assisted ring-opening polymerization of trimethylene carbonate. The polymerizations were carried out in a single-mode microwave oven using ethylene glycol (EG) as the initiator in the absence of any metallic compound catalyst. The temperature-time profiles of the reaction mixture were investigated at different power levels and EG concentrations. The molar mass of the resulting PTMC and TMC monomer conversion by the microwave method is higher than those by the conventional method. Thermal properties of the resulting polymers were studied by differential scanning calorimetry. Microwave irradiation proved to be an effective and efficient method for the preparation of PTMC.
