<P>PROBLEM TO BE SOLVED: To provide a rubber composition which further decreases heat generation while combining butadiene rubber of a high-cis structure. <P>SOLUTION: The rubber composition is obtained by mixing 10-120 pts.wt. of silica with 100 pts.wt. of diene rubber that contains 5-100 wt.% of modified butadiene rubber, wherein the modified butadiene rubber is obtained by modifying butadiene rubber whose cis-content is 90% or more with a nitrone compound that has a nitrogen-containing heterocycle in a molecule. <P>COPYRIGHT: (C)2013,JPO&INPIT |
