하기 화학식으로 나타내어지는 플루오르화된 폴리에테르: Z-X및 하기 화학식으로 나타내어지는 비플루오르화된 폴리에테르: Q- X를 포함하는 경화성 조성물을 제공한다. Z은 p-가 퍼플루오르화된 폴리에테르 기를 나타낸다. Q은 y-가 탄화수소 폴리에테르 기를 나타낸다. 각각의 X및 X기는 독립적으로 작용기를 나타낸다. p 및 y는 ≥ 2의 정수이다. p X기의 적어도 일부는 y X기의 적어도 일부와 반응성이어서, 공유 결합에 의해 가교결합된 중합체 네트워크를 형성한다. 경화성 조성물을 경화시킴으로써 제조되는 하이브리드 플루오로엘라스토머가 또한 개시되어 있다. 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.
