摘　　要：评述了具有殷实应用前景的极性环烯烃共聚物最新研究进展。主要对比了后处理法、前处理法及直接共聚法三种不同的制备途径。后处理法因极性基团通过后处理产生,故不会影响聚合活性,且极性基团含量较高,但步骤繁琐。前处理法使极性基团的保护与聚合过程相耦合,操作较后处理法简便。直接共聚法工艺最为简单,但其催化剂活性还有待进一步提高。同时,在基于制备过程特征的基础上,围绕提高环烯烃及极性基团的有效插入率进行了重点阐述。The polar cyclic olefin copolymer is a promising polymer material which possesses excellent transparency,high heat resistance and refractive index,etc.It can be used in the optical,electrical and medical packaging fields.The latest progress of preparing polar cyclic olefin copolymers was reviewed in this paper.The three synthesis methods such as post-processing,pre-processing and direct copolymerization were compared.Post-processing does not reduce the activity and results in high polar group content.But the process is complex.The protection of polar monomer is coupled in the polymerization process for pre-processing.So it is easier compared to post-processing.Direct copolymerization is the simplest one.However,its catalyst activity should be further improved.Moreover,based on the characteristics of the copolymerization process,improving the incorporation efficiency of both cyclic olefin and polar group should be a main focus on this paper.
