PURPOSE:To provide the titled composition having excellent tear resistance, by adding a hydroxyaromatic compound and a cyanoethyl-substituted imidazole as crosslinking agents to a tetrafluoroethylene-propylene-glycidyl vinyl ether terpolymer. CONSTITUTION:A hydroxyaromatic compound containing hydroxyl group in the molecule and a cyanoethyl-substituted imidazole compound (e.g. 1-cyanoethyl-2- methylimidazole) are added as crosslinking agents to a tetrafluoroethylene- propylene-glycidyl vinyl ether terpolymer. The molar ratio of tetrafluoroethylene/ propylene in the terpolymer is 90/10-55/45, preferably 60/40-50/50, and the content of glycidyl vinyl ether is 0.1-10mol%, preferably 1-5mol%. The amount of the components of the crosslinking agent is 0.1-10pts.wt. each per 100pts.wt. of the terpolymer.
