Abstract

PURPOSE: To provide the titled compsn. having excellent mechanical strength, foaming properties, flexibility, flow characteristic and wear resistance, consisting of 1,2-polybutadiene, a block copolymer of an arom. vinyl compd. with a conjugated diolefin, and 1,4-polybutadiene as main components.
CONSTITUTION: A compsn. consisting of 20W85wt% polybutadiene (A) having a 1,2-bond structure content of 70% or more, a crystallinity of 5W35wt% and an intrinsic viscosity [η] of 0.7 or above (in toluene at 30°C), 10W70wt% block copolymer (B) of an arom. vinyl compd. with a conjugated diolefin, and 5W30wt% polybutadiene (C) having a 1,4-bond structure content of 80% or above, is used as a main component. When necessary, 0W50pts.wt. (per 100pts.wt. said compsn. composed of components A, B and C) process oil and 0W50pts.wt. inorg. filler are incorporated into said compsn. The resulting compsn. is lightweight and has excellent tensile and tear strength, foaming properties, flexibility, flow characteristics and wear resistance as well as excellent low-temperature resistance and snap-back characteristics.
