采用本体聚合和溶液聚合两种方法制备了聚碳酸亚乙烯酯。本体聚合产物主要是交联的，这是由于链自由基和大分子之间的转移反应。在溶液聚合中，由于与溶剂的链转移反应，只能得到可溶的低分子量聚合物，并测定了60°C下N，N-二甲基甲酰胺在碳酸亚乙烯酯聚合中的转移常数CS=0.0228。此外，还对聚碳酸亚乙烯酯及其模型化合物碳酸亚乙酯的氨解和水解进行了研究。
Poly(vinylene carbonate) was prepared via both bulk and solution polymerization. The products of bulk polymerization were mainly crosslinked, which was due to transfer reactions between the chain radicals and macromolecules. In solution polymerization, only soluble and low-molecular-weight polymers could be obtained because of chain transfer reactions with the solvents, and the transfer constant of N,N-dimethylformamide in the polymerization of vinylene carbonate at 60°C, CS=0.0228, was determined. Additionally, aminolysis and hydrolysis of poly(vinylene carbonate) and its model compound – ethylene carbonate were studied, respectively.
