RUBBER COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain a rubber composition by compounding a plurality of diene rubbers with carbon black through controlling the carbon black partitioning amounts in the respective diene rubbers to deviate the carbon black in the respective rubber phases. SOLUTION: The rubber composition is obtained by compounding 100 pts. wt. of a blend rubber component comprising the plurality of diene rubbers with 40-120 pts. wt. of carbon black and 1-20 pts. wt. of a low-molecular weight polymer having a functional group interacting with the carbon black on the molecular chain end and having a polymer structure similar to either one of the diene rubbers.
