The combination of t-Bu-P4 and alcohol was found to be an excellent catalytic system for the controlled/living ring-opening polymerization (ROP) of N,N-disubstituted glycidylamine derivatives, such as N,N-dibenzylglycidylamine (DBGA), N-benzyl-N-methylglycidylamine, N-glycidylmorpholine, and N,N-bis(2-methoxyethyl)glycidylamine, to give well-defined polyethers having various pendant tertiary amino
发现t -Bu-P 4和醇的组合是N,N-二取代缩水甘油胺衍生物(N,N-二苄基缩水甘油胺(DBGA))的受控/活性开环聚合(ROP)的优良催化体系,N-苄基-N-甲基缩水甘油基胺,N-缩水甘油基吗啉和N,N-双(2-甲氧基乙基)缩水甘油基胺,可得到定义明确的聚醚,该聚醚具有各种侧链叔氨基,分子量可预测且分子量分布窄(通常为M瓦特/米n <1.2)。所述吨-Bu-P 4这些单体在室温下在甲苯中的催化ROP以活性方式进行,这已通过MALDI-TOF MS分析,动力学测量和后聚合实验得到了证实。本系统的良好控制性质使得能够生产由缩水甘油胺单体组成的嵌段共聚物。通过用Pd / C处理分别对聚(DBGA)和聚(BMGA)进行脱苄基反应,可以容易地获得分别具有侧链伯和仲氨基侧基的聚醚,即聚(缩水甘油基胺)和聚(缩水甘油基甲基胺)。在氢气氛下在THF / MeOH中的溶液。据我们所知,本报告是缩水甘油
