共聚法合成可熔纺聚丙烯腈树脂

摘要

The methods for preparation of melt-spin nable polyacrylonitrile resin by copolymerization have been reviewed. Some new copolymerization methods have been discussed and evaluated. The conclusions could be drawn that the research t opic should concentrated on free radical emulsion or suspension polymerization b y now. But atomic transfer free radical polymerization should be concerned that might be a most useful method of polymerization controlling in the future.%综述了共聚法合成可熔纺的聚丙烯腈树脂的方法,介绍了国外主要的研究成果,讨论 了自由基乳液聚合、悬浮聚合、交替共聚、活性聚合和模板聚合等聚合方法,并对这些方 法进行了初步评价。指出自由基乳液聚合或悬浮聚合，应该是 国内目前研究的重点，而原子转移自由基聚合有可能成为最有前途的可控聚合方法。
