Abstract
Provided is a rubber-containing graft polymer that can be uniformly dispersed in a thermoplastic resin containing an alloy in a particle size of 100 to 300 nm and can improve strength developability required as a rubber-containing graft polymer. In a rubber-containing graft polymer (A) of the present invention, a rubber to be grafted has a particle size of 100 to 300 nm, a content of an organic solvent insoluble component in the rubber-containing graft polymer (100% by mass) is 92% to 99.5% by mass, and an organic solvent soluble component of the rubber-containing graft polymer has a weight average molecular weight of 250,000 to 700,000.
