摘要

A resin powder of a rubber-containing graft copolymer mixture, the powder being obtained by separately spray-drying a rubber-containing graft copolymer latex and a latex of a rigid non-elastic copolymer having a glass transition temperature of 60 to 150°C, the proportion of the rubber-containing graft copolymer to the rigid non-elastic copolymer being 90-99.9/10-0.1 by weight.
