ABSTRACT OF THE DISCLOSURE A filler-containing polypropylene resin composition and a process for producing the same are disclosed. The composition comprises (a) from 27 to 87% by weight of a polypropylene resin, (b) from 3 to 15% by weight of a modified polypropylene resin containing from 0.1 to 3 mol% of an unsaturated dicarboxylic acid anhydride repeating unit, (c) from 5 to 30% by weight of an ethylene copolymer composed of from 82 to 98.7 mol% of an ethylene repeating unit, from 1 to 15 mol% of an ester repeating unit selected from alkyl acrylates and alkyl methacrylates having from 1 to 8 carbon atoms in the alkyl moiety thereof, and from 0.3 to 3 mol% of an unsaturated dicarboxylic acid anhydride repeating unit, and (d) from 5 to 40% by weight of a filler. The process comprises melt- mixing the components (a), (b), and (d) and then melt- mixing the resulting mixture with the component (c). The resin composition exhibits excellent finishing properties, such as adhesion, coating properties, and printability, as well as improved rigidity and thermal properties.
