Rubber vulcanization ones and its production method, and the polymer composition, the rubber composition and the vulcanization characteristic rubber composition which are used for that

摘要

It designates that vulcanization ones of the nitrile basic content copolymerization rubber which is superior in resistance ozone characteristic are offered as purpose. The nitrile basic content copolymerization rubber (1)40 - 90 weight %, (meta) the methyl acrylate unit is designated as the main structural unit, heating processing in T+20C - T+90C the acrylic resin (2) either glass transition temperature and melted temperature higher one as T, it designates the polymer composition which building a bridge characteristic functional group content contains and becomes per 100g the acrylic resin of 0.01 equal amounts or less (2) mean diameter particle 60 of 10 millimicrons or less - 10 weight %, as the rubber composition, combines the vulcanizing agent here and makes the vulcanization characteristic rubber composition, vulcanizes this and produces rubber vulcanization ones.
