Patent ID: 8207386

Claim:
A method for producing a rubber-like elastic article, comprising: hydrogenating natural polyisoprenoid in the state of latex with hydrogen in the presence of a hydrogenation catalyst in water to obtain a hydrogenated natural polyisoprenoid, and subjecting a rubber composition comprising said hydrogenated natural polyisoprenoid having a degree of hydrogenation of 95% or more or a modified product thereof to molding/forming accompanied by vulcanization, wherein said hydrogenated natural polyisoprenoid has a weight-average molecular weight of 83×10 4 or more and a molecular-weight distribution of 2.0 or more, wherein the catalyst is selected from the group consisting of a homogenous catalyst and a heterogeneous catalyst, wherein the homogenous catalyst is selected from the group consisting of metal salts and metal-containing ionic compounds; wherein said metal salts and metal-containing ionic compounds are selected from the group consisting of nickel carbonate-trialkylaluminum, palladium chloride, and palladium acetate, and wherein the heterogeneous catalyst is a solid catalyst having Pd/CaCO 3 or Pd/C.
