Abstract
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.
