Controlled cationic ring-opening polymerization of L-lactide by organic ion pair:novel approach to isotactic-rich and crystalline polylactide
《Science China Chemistry》2025年第1期394-402,共9页Zhiqiang Ding Mingqian Wang Zijing Zhou Bin Wang Yuesheng Li 
supported by the National Natural Science Foundation of China(52222302)。
Living/controlled cationic ring-opening polymerization(ROP)of L-lactide is a promising approach to isotactic-rich and crystalline poly(L-lactide).In contrast with the unsubstituted lactones,L-LA can not be polymerized...
