摘要:
A copolymer having tetrafluoroethylene units, hexafluoropropylene units, and units independently represented by formula in a range from 0.02 to 2 mole percent, based on the total amount of the copolymer. Rf is a linear or branched perfluoroalkyl group having from 1 to 8 carbon atoms and optionally interrupted by one or more -O- groups, n is from 1 to 6, and m is 0 or 1. The copolymer has a melt flow index in a range from 25 grams per 10 minutes to 35 grams per 10 minutes and has up to 50 unstable end groups per 10 6 carbon atoms. The copolymer can be extruded to make articles, such as insulated cables. A method of making the copolymer is also disclosed.
摘要(中):
基于共聚物的总量,具有四氟乙烯单元,六氟丙烯单元和独立地由式表示的单元范围为0.02-2摩尔%的共聚物。 Rf是具有1至8个碳原子并且任选被一个或多个-O-基团间隔的直链或支链全氟烷基,n为1至6,m为0或1.该共聚物的熔体流动指数为 范围为25克/ 10分钟至35克/ 10分钟,并且每106个碳原子具有多达50个不稳定末端基团。 共聚物可以被挤出以制造制品,例如绝缘电缆。 还公开了制备共聚物的方法。
