摘 要:嵌段共聚物能够带来不同于均聚物和一般共聚物的物化性能,但是嵌段共聚物的大规模应用受限于其高合成难度。在链穿梭聚合提出后的十几年间,有大量嵌段共聚物的合成方法的实现,使得嵌段共聚物的合成和大规模制备成为可能,本文通过提到了线性-高支化线性聚乙烯、乙烯和1-己烯嵌段共聚物、金属低聚物实现三嵌段共聚以及嵌段聚丙烯的合成,这些方法极大的丰富了聚合物的结构和组成方式,提供了有优异性能的聚合物材料。Block copolymers have different physical and chemical properties from homopolymers and general copolymers,but the large-scale application of block copolymers is limited by their high synthesis difficulty.Over the past ten years after the chain shuttling polymerization was realized,a large number of block copolymer synthesis methods have been found,which has made it possible to synthesize and large-scale preparation of block copolymers.This paper mentions the synthesis of linear-highly branched linear polyethylene,ethylene and 1-hexene block copolymers,triblock copolymerization achieved by metal oligomers and block polypropylene which greatly enrich the structure and composition of polymers and provide polymer materials with excellent properties.
