Abstract

PURPOSE: A composition providing a vulcanized material having improved wear resistance and tensile strength, having improved vulcanization return with keeping properties of natural rubber, obtained by blending natural rubber or polyisoprene with a specific polybutadine and a styrene-butadiene copolymer.
CONSTITUTION: (A) 20W75wt% natural rubber and/or polyisoprene is blended with (B) 10W50wt% polybutadiene having a vinyl bond amount of 1W25wt% and (C) 15W60wt% styrene-butadiene copolymer having a styrene content of 5W 60wt% and a vinyl bond amount of the butadiene part of 35W80wt% as three ingredients, or blended with (D) 15W60wt% polybutadiene having a vinyl bond amount of 35W60wt% and (E) 10W50wt% styrene-butadiene copolymer a styrene content of 5W35wt% and a vinyl bond amount of the butadiene part of 1W 25wt% as three ingredients as raw material rubber. Preferably the mixture of the ingredients B+C or the ingredients D+E has a styrene content of 10W 35wt% and a vinyl bond amount of the butadiene of 30W60wt%.
