Publication number: 20220298299Abstract: The present disclosure belongs to the field of organic synthesis, and particularly relates to a ring-opening polymerization method for a cyclic monomer. A specific solution is that a Lewis acid-base pair is used to catalyze ring-opening polymerization of the cyclic monomer in the presence of an initiator. By using the Lewis acid-base pair as a catalyst, on one hand, a range of a ring-opening polymerization catalyst is widened, and on the other hand, this catalyst achieves a higher catalytic efficiency and is milder in comparison with previously reported strong acid or strong base catalysts. In addition, through a bifunctional activation mechanism, this catalyst system activates the monomer and simultaneously activates the initiator or a chain end, and has the characteristics of high efficiency in comparison with the reported monomer activation mechanism or chain end activation mechanism.Type: ApplicationFiled: September 8, 2020Publication date: September 22, 2022Inventors: Kai GUO, Zhiwei YAO, Zhenjiang LI, Chan ZHANG, Yuejia ZHU, Lei ZHANG, Zikun LUO
