    • The present invention provides a vulcanized rubber material having improved heat resistance while maintaining ozone resistance of an epihalohydrin rubber, and a rubber composition for vulcanization for producing the same. The invention further provides a vulcanized rubber material and a rubber composition for vulcanization, that can achieve the above objects without using an organonickel compound having a concern about toxicity, or if used, using the same as less as possible. The present invention relates to a rubber composition for vulcanization comprising (a) 100 parts by weight of an epihalohydrin rubber, (b) 0.01 to 0.5 part by weight of a copper salt of dithiocarbamic acid, (c) an acid acceptor, and (d) a polythiol type vulcanizing agent or a polyol type vulcanizing agent, a vulcanized rubber material obtained by vulcanizing the composition, and an automotive rubber part comprising the vulcanized rubber material.
    • 本发明提供一种具有改善的耐热性同时保持表卤代醇橡胶的耐臭氧性的硫化橡胶材料和用于制造硫化橡胶的橡胶组合物。 本发明还提供一种硫化橡胶材料和用于硫化的橡胶组合物,其可以在不使用关于毒性的有机镍化合物的情况下实现上述目的,或者如果使用,则尽可能少地使用它们。 本发明涉及一种用于硫化的橡胶组合物,其包含(a)100重量份的表卤代醇橡胶,(b)0.01至0.5重量份的二硫代氨基甲酸铜盐,(c)酸受体和(d )多硫醇型硫化剂或多元醇型硫化剂,通过硫化组合物得到的硫化橡胶材料和包含硫化橡胶材料的汽车橡胶部件。

    • An object of the invention is to provide a process for producing an ether (co)polymer in which molecular weight control is easy and post treatment of the reaction liquid after polymerization (solvent recovery, etc.) is easy; a chain transfer agent to be used in the production process; and an ether (co) polymer obtained according to the production process. The process for producing an ether (co) polymer of the invention is characterized in that an ether monomer is polymerized in a solvent, in the presence of a catalyst comprising a condensate of an organotin compound and an alkyl phosphate, and a chain transfer agent comprising, as the major ingredient thereof, an aliphatic polyalcohol of the following general formula (I), thereby producing an ether (co)polymer. Cx(OH)yHz. In the formula, X indicates an integer of from 2 to 8; Y indicates an integer of from 2 to (2X+2); Z indicates an integer of 2X+2−Y; and the hydroxyl groups are bonded at any positions.
