THERMOPLASTIC POLYMER COMPOSITION, PRODUCTION THEREOF, AND INJECTION MOLDED ARTICLE PRODUCED THEREFROM

摘要

PURPOSE: To obtain a thermoplastic polymer compsn. improved in adhesive properties and in adhesion to a coating film so that the step of cleaning with a TCE vapor and/or the step of treating with a primer can be omitted without detriment to the moldability and mechanical strengths. CONSTITUTION: 100 pts.wt. polymer component comprising 20-85 pts.wt. olefin resin and 15-80 pts.wt. elastomer is compounded with 0.1-30 pts.wt. terpene resin and/or its hydrogenation product, then compounded with 4 pts.wt. or lower cross-linker if necessary, and melt mixed and kneaded with a kneader.
