四氟乙烯和全氟化烯丙基醚共聚物
Abstract:
本发明公开了一种共聚物，所述共聚物具有四氟乙烯单元和由式(I)独立地表示的单元，由式(I)独立地表示的单元基于所述共聚物的总量计在0.02摩尔％至2摩尔％的范围内。Rf为具有1至8个碳原子并任选地被一个或多个‑O‑基团间断的直链或支链的全氟烷基基团，n独立地为1至6，并且z为0、1或2。所述共聚物的熔体流动指数在20克/10分钟至40克/10分钟范围内。所述共聚物可挤压以制备制品，诸如绝缘线缆。本发明还公开了一种制备所述共聚物的方法。
Abstract(English):

A copolymer having tetrafluoroethylene units and units independently represented by formula (I) 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 independently from 1 to 6, and z is 0, 1, or 2. The copolymer has a melt flow index in a range from 20 grams per 10 minutes to 40 grams per 10 minutes. The copolymer can be extruded to make articles, such as insulated cables. A method of making the copolymer is also disclosed.
