Rubber composition comprising a styrene-butadiene block copolymer having two kinds of blocks |
| abstract |
A rubber composition containing at least 20% by weight of a styrene-butadiene block copolymer consisting of a block (A) and a block (B) characterized in that: (i) the block (A) is a styrene-butadiene copolymer block having the content of styrene of 10-80% by weight and the average content of the vinyl bonds in the butadiene portion of 30-70% by weight; (ii) the block (B) is a polybutadiene block with the average content of the vinyl bonds in the butadiene portion being not more than 60% by weight (iii) the styrene-butadiene block copolymer contains at least 20% by weight of each of the block (A) and the block (B); (iv) the average content of the vinyl bonds in the butadiene portion of the block (A) is greater by at least 5% by weight than that of the block (B); (v) the glass transition temperature of the block (A) is higher by at least 30 DEG C. than that of the block (B); (vi) the whole content of the bound styrene in the above block copolymer is 5-40% by weight; (vii) the ratio Mw/Mn between the weight average molecular weight Mw and the number average molecular weight Mn of the block copolymer is 1.8-5.0 when calculated as polystyrene according to the gel permeation chromatogram; and (viii) the Mooney's viscosity (ML1+4100 DEG C.) of the block copolymer is 20-150. |
