A resin composition comprising a modified polypropylene obtained by reacting a polypropylene with a liquid rubber and maleic anhydride in a solvent in the presence of a radical generator, another polyolefin and, if desired, an inorganic and/or an organic filler. The resin composition has excellent coating, adhesion and plating properties.

Resin compositions containing modified polypropylene

A process for producing a resin composition having excellent plating properties comprising heating a mixture consisting substantially of 100 parts by weight of a polyolefin resin, 5 to 150 parts by weight of an inorganic filler, 1 to less than 20 parts by weight of a liquid rubber, 0.1 to 10 parts by weight of an unsaturated carboxylic acid and 0.001 to 10 parts by weight of a radical generator at 110.degree. to 280.degree. C. in the absence of solvents.

Process for production of resin compositions with excellent plating

Composition for extrusion molding comprising a blend of 90 to 30 weight percent of thermoplastic resin and 10 to 70 weight percent of inorganic filler and a modifier selected from sorbitan fatty acid esters and polyoxyethylene sorbitan fatty acid esters in an amount of 0.1 to 5 parts by weight based upon 100 parts by weight of the blend.

Thermoplastic resin composition suitable for extrusion molding

A process for producing modified polypropylene comprising reacting polypropylene with a liquid rubber and maleic anhydride in a solvent in the presence of a radical generator.
