FLEXIBLE POLYMER COMPOSITION, COMPOSITE FORMED ARTICLE HAVING PORTION COMPOSED OF THE SAME COMPOSITION, AND PRODUCTION OF THE SAME FORMED ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a flexible polymer composition, improved in adhesive properties to have excellent thermal fusibility with a thermoplastic polymer, and also to provide a composite formed article composed of the formed portion of the above light polymer composition and another formed portion of a thermoplastic polymer, which are thermally fused to each other at a high adhesive strength. SOLUTION: This flexible polymer composition is composed of (A) a flexible polymer and (B) a syndiotactic polypropylene at 1 to 30 pts.wt. per 100 pts.wt. of the component A. This composite formed article is composed of the formed portion (I) of the above light polymer composition and formed portion (II) of a thermoplastic polymer, at least one of glass transition temperature and melting point of which is 80 deg.C or higher, as determined by a differential scanning calorimeter, wherein these portions I and II are thermally fused to each other.
