PROBLEM TO BE SOLVED: To provide a curable composition affording a polyoxyalkylene-based cross-linked rubber having little surface tack and good surface properties and to provide the cross-linked rubber. SOLUTION: The curable composition is composed of (A) a polyoxyalkylene polymer having >1 alkenyl groups in one molecule, (B) a compound having at least 2 hydrosilyl groups in one molecule and (C) a hydrosilylating catalyst. (D) Fumed silica surface treated with a silicone oil is further used in the curable composition. Thereby, the polyoxyalkylene-based cross-linked rubber having the little surface tack and good surface properties is obtained. COPYRIGHT: (C)2008,JPO&INPIT
