Abstract
Provided is a rubber-containing graft polymer which is excellent in mechanical strength such as weld strength or impact strength, required as a rubber-containing graft polymer. A rubber-containing graft polymer (A) of the present invention is a rubber-containing graft polymer having a graft chain, in which when the rubber-containing graft polymer is mixed with an organic solvent and separated into an organic solvent insoluble component and an organic solvent soluble component, a caprolactone unit is contained in a graft chain contained in the organic solvent insoluble component.
