PURPOSE:To provide the titled resin compsn. having excellent bonding power to a deposited metal film, by a method wherein modified polypropylene is blended with a mixt. of polypropylene and talc. CONSTITUTION:An unsaturated carboxylic acid is added to polypropylene to produce modified polypropylene. Alternatively, polypropylene is reacted with terminal- hydroxylated polybutadiene having a number-average MW of 500-1,000 and an unsaturated carboxylic acid in the presence of a free-radical generating agent to produce modified polypropylene. 5-15pts.wt. of the modified polypropylene (B) so produced is blended with 100pts.wt. of a mixt (A) of 60-90wt% of polypropylene and 40-10wt% of talc. |
