with poly(ε-caprolactone) via the polymerization of 4-azido-1-(prop-2-yn-1-yloxy)butan-2-ol (N3hydroxypropargyl) and ε-caprolactone monomers is reported. For this purpose, a click reaction and ring-opening polymerization (ROP) were combined and carried out simultaneously. N3hydroxypropargyl served as both the ROP initiator and a monomer for the click polymerization. Thus, an in situ “grafting-through
通过4-叠氮基-1-(prop-2-yn-1-yloxy)butan-2-ol(N 3羟基炔丙基)和ε-己内酯的聚合反应,一锅构建聚三ε-己内酯接枝的聚三唑报告了单体。为此,将点击反应和开环聚合(ROP)合并并同时进行。N 3羟基炔丙基既用作ROP引发剂又用作点击聚合的单体。因此,在一个锅中建立了一种现场“从头到尾移植”策略。将CuBr和Sn(Oct)2用作双重催化剂,并且聚合反应在N 2气氛下在120℃下进行。
