Abstract

PURPOSE: To provide a rubber composition being excellent in plasticity in an unvulcanized condition, tackiness and forming a vulcanized article with good mechanical properties suitable for a tread and a side wall of a tire obtained by compounding a cyclized compound of a conjugated diene (co)polymer to a natural or a synthetic rubber.
CONSTITUTION: To 100pts.wt. or a vulcanizable natural or synthetic rubber, e.g., styrene-butadiene copolymer, polyisoprene rubber, 4W40pts.wt. of a cyclized compound obtained by cyclizing a conjugated diene (co)polymer is compounded to obtain a composition. Said cyclized compound is obtained by cyclizing a polymer such as liquid polybutadiene and liquid polyisoprene by a protonic acid or the like and, particularly, is preferred a compound being (semi)solid at a room temp. with bromine value of 40 or more and MW of 400W100,000.
EFFECT: Excellent in cut resistance.
