Patent ID: 8304481

Claim:
A process for producing a thermoplastic resin composition comprising: 40 to 99 parts by weight of a resin component (component A) comprising 50 to 85% by weight of an aromatic polycarbonate resin (component A1) and 50 to 15% by weight of a thermoplastic polyester resin (component A2) with the proviso that a total content of the components A1 and A2 is 100% by weight; 1 to 60 parts by weight of a granular talc (component B) having a bulk density of 0.4 to 1.5 g/mL which is obtained by granulating a talc having an average particle size of 0.1 to 10 μm; and 1 to 35 parts by weight of a rubber polymer (component C), said process comprising using said granular talc (component B) which has the particle size in which a proportion of a 500 μm-mesh screen residue thereof is not less than 97% by weight, which granular talc (component B) is produced by granulating said talc by using a binder and a lubricant and controlling the water content in the granular talc to not more than 1%, which binder comprises sodium carboxymethyl cellulose (CMC) blended in the granular talc (component B) in an amount of 0.01 to 5% by weight, which lubricant is water blended in an amount of 10 to 150 parts by weight on the basis of 100 parts by weight of a total amount of the material talc and binder.
