作为合成新高分子化合物最重要方法的共聚反应,具有很大的意义,它能使我們按照需要而改变聚合物的性貭。如合成橡胶中的异丁橡胶(异丁烯与丁二烯的共聚物),丁苯橡胶(丁二烯与苯乙烯的共聚物),丁腈橡胶(丁二烯与丙烯腈的共聚物);合成树脂与合成纤維中的沙綸(Saran)(氯乙烯与偏二氯乙烯的共聚物),維尼縈与維尼縈HH(Vinyon HH)(氯乙烯与醋酸乙烯酯的共聚物),維尼縈N(氯乙烯与丙烯腈的共聚物)等,均是近代共聚物中最重要的代表物。
As the most important method for the synthesis of new macromolecular compounds, copolymerization has great significance, it allows us to change the nature of the polymer as needed. Such as synthetic rubber in the butyl rubber (isobutylene and butadiene copolymer), styrene butadiene rubber (butadiene and styrene copolymer), nitrile rubber (butadiene and acrylonitrile copolymer); Synthesis Among resins and synthetic fibers, Saran (a copolymer of vinyl chloride and vinylidene chloride), Vinyon HH (a copolymer of vinyl chloride and vinyl acetate), vinylnitrone N Vinyl chloride and acrylonitrile copolymer), etc., are the most important representatives of modern copolymer.
