功能化已成为实现高分子材料高性能化的重要途径,高分子材料的功能化已从端基官能化向链中官能化发展。本文评述了基于活性阴离子聚合方法高枝化聚合物及链中功能性聚合物的合成方法。以实现链中功能性聚合物“定性、定位、定量”为目标,通过硅氧键(DPE-SiO)、硅氢键(DPE-SiH)与功能性试剂之间的转换反应将目标官能团键入到聚合物链中。系统评述了复杂拓扑结构链中功能性高枝化聚合物的合成方法以及结构与性能之间的构效关系。
Functionalization has become an important way to realize the high performance of polymer materials. The functionalization of polymer materials has been developed from terminal functionalization to functionalization in the chain. This paper reviews the synthesis of hyperbranched polymers and functional polymers in the chain based on living anionic polymerization. In order to achieve functional polymers in the chain, “targeting, targeting, quantification” as the goal, the target functional groups were transferred through the exchange reaction between silicon-oxygen bond (DPE-SiO) Type into the polymer chain. The synthesis method of functional hyperbranched polymers in complex topological chain and the structure-activity relationship between structure and properties were systematically reviewed.
