This invention relates to fluorohydrocarbon polymers which are modified by the incorporation of substitiuents bearing a functional group such as vinyl, allyl, acrylate, alkoxysilane, amido, sulfonic acid salt, pyridine, carboxylic ester and carboxylic salt. The functional groups may be further reacted to obtain branching, grafting or crosslinking of the polymers. Copolymers of vinylidene fluoride and hexafluoropropene such as VITON A rubber and KYNAR FLEX 2801 plastomer, are typical of the class of fluorohydrocarbon polymers which are modified to obtain the new materials of this invention.
本发明涉及通过加入带有乙烯基、烯丙基、丙烯酸酯、烷氧基硅烷、氨基、磺酸 盐、吡啶、羧酸酯和羧酸盐等官能团的取代基而改性的氟烃聚合物。官能团可进一步反应,以获得聚合物的分支、接枝或交联。偏氟乙烯和六氟丙烯的共聚物,如 VITON A 橡胶和 KYNAR FLEX 2801 弹性体,就是典型的氟烃聚合物,通过改性可获得本发明的新材料。
