Abstract

PURPOSE: To provide the title composition of high workability, capable of affording a sealant having high thermal stability, elasticity, and sealing effect, comprising a vulcanizing agent and a low-molecular weight rubber consisting of a block copolymer composed of isoprene and butadiene.
CONSTITUTION: The objective composition comprising a low-molecular weight rubber, a vulcarizing agent, and, if required, other ingredients. Said low-molecular weight rubber consists of a block copolymer composed of isoprene and butadiene and having a viscosity-average molecular wight of 7,000W150,000. Especially, the block copolymer mentioned above is desired to have a weight ratio isopene/butadiene of 25/75W85/15, or have the formula B-I-B, B-I, (B-I)n, or (B-I)n-B (B is a polybutadiene block; 1 is a polyisoprene block, n is 2W10).
