Abstract

PURPOSE: To titled rubber composition suitable for a car tire, etc., which is prepared by compounding natural rubber and/or polyisoprene rubber, with amorphous polybutadiene having a specified range of Mooney viscosity.
CONSTITUTION: The titled rubber composition is obtained by compounding (A) 30W90pts.wt. natural rubber and/or polyisoprene rubber, with 70W10pts.wt. polybutadiene, containing 60W90wt% 1,2 linkage and having Mooney viscosity, on JISK6300, of 20W90 at 120°C. It is possible to compound as a filler, 50W120pts.wt. carbon block with 100pts.wt. rubber.
