Butadiene polymer composition

摘要

A butadiene polymer composition having incorporated the following stabilizers therein: A phenolic compound (I) of the formula: <IMAGE> wherein R1 represents a C1-C4 alkyl group, and a sulfur-containing compound (II) represented by the general formula, <IMAGE> wherein R2 and R3 independently represent a hydrogen atom or a C1-C6 alkyl group, and R4 represents a C3-C18 alkyl group, wherein the weight ratio of (I) to (II) is 1 to 0.5-10. The butadiene polymer composition of the present invention is quite effective to prevent gel formation caused by heat, especially in the absence of oxygen.
