PRODUCTION METHOD OF STYRENE-BASED THERMOPLASTIC ELASTOMER COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a production method of a styrene-based thermoplastic elastomer composition having an excellent property as a sealing material in good workability with a low equipment cost. SOLUTION: The production method includes a process of dissolving the styrene-based thermoplastic elastomer of 100 parts wt. to the liquid softener of 200 to 400 parts wt. by heating in a mixing vessel with stirrer. It is a desirable mode to add an adhesiveness imparting agent such as a styrene resin, after dissolving.
