(Meth)acryloyl group-modified ethylene-alpha-olefin copolymer, production method thereof and rubber composition

   
   

An (meth)acryloyl group-modified ethylene-.alpha.-olefin copolymer (A) which has (meth)acryloyl group as a the side-chain thereof, wherein the intrinsic viscosity [.eta.] was 0.01 to 10 dl/g measured in decalin at a temperature of 135.degree. C.; and a rubber composition which comprises said (meth)acryloyl group-modified ethylene-.alpha.-olefin copolymer, a vulcanizing agent, and/or a crosslinking agent; in addition, a liquid curable rubber composition which comprises, component (A), reactive diluent (D), and if necessary, photopolymerization initiator (E).

(copolímero grupo-modificado meth)acryloyl de ethylene-.alpha.-olefin (a) que tiene (grupo del meth)acryloyl como el side-chain de eso, en donde la viscosidad intrínseca [ el eta. ] era 0.01 a 10 dl/g medidos en decalin en una temperatura de 135.degree. C.; y una composición de goma que abarca dicho (meth)acryloyl grupo-modifico' al copolímero de ethylene-.alpha.-olefin, a un agente de vulcanización, y/o a agente de reticulación; además, una composición de goma curable líquida que abarca, componente (a), diluyente reactivo (d), y en caso de necesidad, iniciador del photopolymerization (e).
