Summary:PROBLEM TO BE SOLVED: To provide a process for producing a surface-modified rubber molded product which improves the mold release characteristics and sliding properties with various rubber products on vulcanization and remarkably improves the durability of the mold release performance. SOLUTION: A rubber composition comprising a modified butyl rubber composition (A) including a modified butyl rubber (1) obtained by reacting a butyl rubber with a compound (a) having a nitroxide free radical which is stable in the presence of oxygen at normal temperatures, a radical initiator (b), and a di- or multi-functional radically polymerizable monomer (c) or a modified butyl rubber composition (B) comprising a modified butyl rubber (2) obtained by reacting a butyl rubber with the compound (a) and the radical initiator (b) and the monomer (c) and an organic peroxide is molded into a uncrosslinked rubber molded product, and a siloxane compound having a (meth)acryloyl group is applied onto the surface of this uncrosslinked rubber molded product, and the resulting product is subjected to heat treatment.
