摘　　要：无论从生物大分子还是合成高分子,均表明大分子链拓扑结构对于材料性能具有重要的作用。探索聚合物分子链拓扑结构与材料性能的关系一直是高分子材料科学研究的重要课题。活性/可控聚合技术为特定拓扑结构的分子链(如:梳形聚合物)设计合成提供了有效途径,进而可以方便地调控聚合物的分子结构及其性能。针对梳形聚合物的合成,目前主要采用三种合成策略,分别是"Graft onto"策略、"Graft through"策略和"Graft from"策略。结合作者课题组的工作,本文综述了以聚烯烃和聚苯乙烯为基础的梳形(共)聚合物的可控合成以及结构与性能关系的研究进展,重点阐述了长链支化结构参数(支链长度、支链密度和化学组成)对于聚合物熔体行为、发泡行为和结晶行为的影响规律。As the topological structure of macromolecular chains is very important to the properties of the materials, the relationship between the topological structure of polymer chains and the properties of materials has always been an important topic in the field of polymer materials. Living/controlled polymerization provides a variety of methods for the controlled synthesis of comb-like polymers, through which the topological structure of comb-like polymers can be easily regulated. Currently, there are three main synthesis strategies adopted, namely "Graft onto" strategy, "Graft through"strategy and "Graft from" strategy. Combined with author′s research work, this paper summarizes the progress in the polyolefin and polystyrene based comb-like(co)polymers, including the synthesis of comb-like polymers with well-defined structure, and the relationship between chain topological structure and performance of the controllable synthesis of comb-like(co)polymers, which focus on the effect of long chain branched structure parameters(branched chain length, density and chemical composition of branch chain) on melt behavior, foaming behavior and crystallization behavior of comb-like(co)polymers.
