【摘要】：超支化聚合物由于其独特的树枝状结构和物理化学性质,已经得到了广泛关注及应用.而基于炔类单体的点击聚合作为一类简单、高效的聚合反应已被广泛用于超支化聚合物的制备.本文对近5年利用叠氮-炔和巯基-炔点击聚合制备超支化聚合物的工作进行了简要综述.其中,Cu(I)催化的叠氮-炔点击聚合可制备1?4-立构规整的超支化聚三唑;Ru(II)催化的叠氮-炔点击聚合可制备1?5-立构规整的超支化聚三唑;活化的炔类单体和叠氮单体的无金属催化点击聚合可得到1?4-异构体含量高(高达91.7%)的超支化聚合物;而光引发?热引发及自发的巯基-炔点击聚合可制备含硫的超支化聚合物.此外,对所制备的超支化聚合物的功能和应用进行了简单介绍,最后还简单讨论了点击聚合制备超支化聚合物方面的可能发展方向.
[Abstract]:Hyperbranched polymers have been widely used because of their unique dendritic structure and physical and chemical properties. Highly efficient polymerization has been widely used in the preparation of hyperbranched polymers. In this paper, the preparation of hyperbranched polymers using azido-acetylene and mercapto-acetylene click-polymerization in recent 5 years is briefly reviewed. Nitrogen-acetylene click polymerization can be used to prepare 1? 4-orthotropic hyperbranched polytriazolium triazole II) catalyzed azido-acetylene click polymerization can be used to prepare 1? 5-orthotropic hyperbranched polytriazole; activated acetylene monomer and azide monomer catalyzed by non-metal-catalyzed click polymerization to obtain 1? A hyperbranched polymer with a high content of 4-isomers (up to 91.7%); and photo-initiated? The hyperbranched polymers containing sulfur can be prepared by thermal initiation and spontaneous mercapto-acetylene click polymerization. In addition, the functions and applications of the prepared hyperbranched polymers are briefly introduced. Finally, the possible development in the preparation of hyperbranched polymers by click polymerization is briefly discussed.
