    摘要: A manufacturing method for a surface-modified rubber molded body is described. An uncross-linked rubber molded body is made of a rubber composition containing an organic peroxide and a modified butyl rubber composition (A) containing a modified butyl rubber (1) where a compound (a) with a stable nitroxide free radical in the molecule at ambient temperature in the presence of oxygen, a radical initiator (b), and a radical polymeric monomer (c) with at least difunctionality are reacted with butyl rubber, or a modified butyl rubber composition (B) where the monomer (c) is added to a modified butyl rubber (2) where the compound (a) and the radical initiator (b) are reacted with butyl rubber. A siloxane compound having a (meth)acryloyl group is applied onto the surface of the uncross-linked rubber molded body. The uncross-linked rubber molded body is then heat-treated.
