A powdered resin composition which comprises 100 parts by weight of a graft polymer containing a rubber as the backbone polymer and prepared by emulsion polymerization with a higher fatty acid salt, 0.1 to 10 parts by weight of a crosslinked polymer composed of 30 to 60 wt% of methyl methacrylate, 65 to 35 wt% of an aromatic vinyl monomer, 0.1 to 25 wt% of a crosslinking monomer, and 0 to 30 wt% of other copolymerizable monomer, and 0.1 to 10 parts by weight of a lubricant and which is excellent in powder characteristics at ordinary and low temperatures, particularly blocking resistance. The composition is remarkably improved in powder characteristics in low-temperature storage as compared with the rubber-rich graft copolymers of the prior art used as impact modifiers for thermoplastic resins. |
