A powdery resin composition having excellent ordinary temperature and low temperature powder characteristics, in particular, excellent blocking resistance, and comprising 100 parts by weight of a graft copolymer which contains a rubber as a trunk polymer and which is obtained by emulsion polymerization using a higher fatty acid salt, 0.1 to 10 parts by weight of a crosslinked polymer of 30 to 60% by weight of methyl methacrylate, 65 to 35% by weight of an aromatic vinyl monomer, 0.1 to 25% by weight of a crosslinking monomer and 0 to 30% by weight of other copolymerizable monomer, and 0.1 to 10 parts by weight of a lubricant. According to the present invention, powder characteristics in low temperature storage of conventional graft copolymers containing a large amount of a rubber, which have been used as impact modifier for vinyl chloride resins, can be remarkably improved. |
