Abstract
A curable composition comprises a fluorinated polyether represented by the formula: Z—Xand a nonfluorinated polyether represented by the formula Q-XZrepresents a p-valent perfluorinated polyether group. Qrepresents a y-valent hydrocarbon polyether group. Each Xand Xgroup independently represents a functional group. p and y are integers ≥2. At least some of the p Xgroups are reactive to at least some of the y Xgroups to form a covalently cross-linked polymer network. Hybrid fluoroelastomers made by curing the curable compositions are also disclosed.
