pendant groups of varying sizes were polymerized via ring opening metathesis polymerization using Grubbs catalyst 2nd generation (G2). The rate of polymerization depended on the size of the pendant groups attached to the cyclobutene rings, with longer side‐chains producing slower polymerization rates and narrower molecular weight distributions. The polymerization of these new molecules proceeded with
使用第二代格鲁布斯催化剂(G2),通过开环易位聚合,将含有不同大小侧基的环戊烯进行聚合。聚合速率取决于连接到环丁烯环上的侧基的大小,较长的侧链产生较慢的聚合速率和较窄的分子量分布。这些新分子的聚合以一级动力学进行,这与活性聚合一致。扩链实验生产的多分散指数低于1.33的环丁烯基二嵌段共聚物。本报告中的合成方法将允许使用G2来获得比降冰片烯类似物和环辛烯部分衍生的侧基密度更高的新型复杂聚合物结构。©2017 Wiley Periodicals,Inc.J. Polym。科学,A部分:Polym。化学2017年,55,1929-1939
