Abstract

PURPOSE: The titled composition with little energy loss slightly swelling when extruded, and enhanced dimentional stability and modulus of elasticity, which is prepd. by compounding a microfine org. short fiber having a glass transition temp. of the amorphous portion in a specified range.
CONSTITUTION: A cord-coating rubber composition consisting of an unvulcanized rubber composition prepd. by compounding 100pts.wt. rubber selected from a natural rubber, synthetic polyisoprene rubber, polybutadiene rubber and styrene- butadiene copolymer rubber with 10W100pts.wt. carbon black and 3W30pts.wt. microfine org. short fiber of 0.8W30μm average length and 0.02W0.8μm average diameter in a proportion of 8W400, having a glass transition temp. of the amorphous portion lower than 30°C or higher than 120°C and a melting point of the crystal portion higher than 160°C, which has a swelling volue ≤130% when extruded at 100°C.
