PROBLEM TO BE SOLVED: To provide a rubber-based composition which is excellent in softness (touch) and mechanical strenghts and also makes possible the stabilization of the quality to improve the productivity. SOLUTION: The rubber-based composition, consisting of (A) a crosslinkable rubbery polymer and (B) a thermoplastic resin, is characterized in that the composition is a partially or completely crosslinked rubber-based composition and is obtained by using a crosslinking agent comprising (C) a crosslinking initiator, a multifunctional monomer and a monofunctional monomer, particularly with the crosslinking initiator (C) being an organic peroxide, the multifunctional monomer being a monomer having a plurality of vinyl groups and the monofunctional monomer being a vinyl monomer. |
