POLYPROPYLENE-BASED COATED MOLDED PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a polypropylene-based coated molded product by coating a crystalline polypropylene molded product containing an electroconductive carbon with a coating component containing a polar group-containing propylene-based polymer. SOLUTION: The polypropylene-based coated molded product is obtained by applying (A) the coating component comprising a polar group-containing propylene-based polymer composed of a main chain composed of the propylene-based polymer having characteristics: (1) a polymer produced by a single site catalyst and (2)≤1 wt.% insoluble matter when dissolved in a concentration of 10 wt.% in heptane at 98°C and a side chain containing a carboxylic group, a carboxylic acid anhydride group or a carboxylic acid ester group to (B) the base material which is a molded product of a resin composition composed of a crystalline polypropylene and an electroconductive carbon and having≥30% surface glossiness. The polypropylene-based coated molded product is excellent in adhesion of coated film and balance of physical properties such as rigidity and impact resistance and has high glossiness and conductivity.
