Title:
METHOD FOR PRODUCING ELASTOMER COMPOSITION
Document Type and Number:
Japanese Patent JP3941551
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for the industrial production of an elastomer composition usable as a base polymer of an adhesive exhibiting initial tackiness at low temperature and adhesive force at high temperature and having excellent processability.
SOLUTION: A conjugated diene polymer (B) is newly produced by adding a polymerization initiator and a conjugated diene monomer to a solution containing a block copolymer (A) having a [terminal polyaromatic vinyl block- poly(conjugated diene) block] structure and containing ≥2 terminal polyaromatic vinyl blocks and polymerizing the monomer.
