A curable composition comprises a fluorinated polyether represented by the formula: Z1—X1p and a nonfluorinated polyether represented by the formula Q1-X2yZ1 represents a p-valent perfluorinated polyether group. Q1 represents a y-valent hydrocarbon polyether group. Each X1 and X2 group independently represents a functional group. p and y are integers ≥2. At least some of the p X1 groups are reactive to at least some of the y X2 groups to form a covalently cross-linked polymer network. Hybrid fluoroelastomers made by curing the curable compositions are also disclosed.
一种可固化组合物包括由式Z1-X1p 和由式 Q1-X2yZ1 代表对价
