Abstract
PURPOSE:To provide the titled composition outstanding in both crack and cut resistances, comprising specified proportion of natural rubber etc. and a polybutadiene with the cis content predominant and the difference between the Shore A hardnesses at the corresponding respective specified temperatures being specific value. CONSTITUTION:The objective composition comprising (A) 10-60pts.wt. of a polybutadiene with the cis content of >=98% and the difference DELTAA between the Shore A hardnesses at -5 deg.C and 23 deg.C respectively being <=4 and (B) 40-90 pts.wt. of natural rubber and/or a diene-based synthetic rubber.
