Abstract

Atactic polycarbonate with the content of carbonate units above 99% has been synthesized by the copolymerization of racemic propylene oxide and carbon dioxide mediated by the salen complex of cobalt and bis(triphenylphosphine)iminium chloride. Its biodegradation under accelerated composting conditions has been studied. It has been shown that ammonia is the main abiotic degradant during the composting of poly(propylene carbonate). Polymer degradation proceeds at a low rate, is accompanied by a gradual decrease in molecular weight, and yields propylene glycol.

加速堆肥条件下氨在聚碳酸丙烯酯降解中的作用

以钴和二（三苯基膦）氯化亚胺的salen配合物为介质，以外消旋环氧丙烷和二氧化碳为共聚反应，合成了碳酸单位含量在99%以上的无规聚碳酸酯。对其在加速堆肥条件下的生物降解进行了研究。研究表明，在碳酸丙烯酯堆肥过程中，氨是主要的非生物降解剂。聚合物降解以低速率进行，伴随着分子量的逐渐减少，并产生丙二醇。
