cyclic monomer

The three cyclic carbonate monomers were ring-opening polymerized in bulk in the case of the catalyst Al ( O iBu) 3, monomer-to-catalyst ratio of 100 and reaction time of 16 hours.

以三异丁氧基铝为催化剂，单体/催化剂摩尔浓度比为100，反应时间16h，在190℃或210℃下本体开环聚合，对它们的开环聚合进行了初步的研究。

At present, the major method to synthesize polyester is the ring opening polymerization ( ROP) of cyclic ester monomer with the metal alkoxides as initiators.

目前合成聚酯的方法主要是利用金属配合物催化/引发环化酯单体开环聚合。

It has also been found that, the polymerization rate of cyclic phosphoester monomer is highly depended on the structure of pendant side group and the ring substituent group when using stannous octoate as the catalyst.

研究还发现，以异辛酸亚锡为催化剂的磷酸酯单体的聚合速率与磷酸酯单体的侧基、环取代基密切相关，而且可以方便利用聚磷酸酯侧基对高分子进行功能化修饰。
