摘要 综述了自由基聚合在α-烯烃均聚及与功能性单体共聚制备功能化聚烯烃方面的研究进展。自由基聚合方法具有易操作、成本低等优点,特别是随着活性自由基聚合的发展,使对通过自由基聚合所得聚合物的结构进行精确调控成为可能。目前在α-烯烃均聚方面,通过选择适当的溶剂以及添加有机锂盐,使在相对温和条件下自由基引发α-烯烃合成高分子量聚合物成为可能。在共聚体系中,路易斯酸或布伦特斯酸的引入可以大幅提高共聚物中α-烯烃的含量。 Using radical technology in non-polar monomer homopolymerization or copolymerization with functional monomers was summarized.Compared with other polymerization methods,free radical polymerization has the andvantages of facilitated operation,low cost,etc.With the development of controlled/living radical polymerization(LRP),polymer with well-defined structures can be synthesized.When selecting suitable solvent or adding organic lithium salt,α-olefins homopolymerization can be successively carried out under relatively mild conditions.The introduction of Lewis acid or Bronsted acid can significantly increase the content ofα-olefins in the copolymer.
