摘要：
A process for preparing an ABS graft copolymer, which comprises a step for isolating the graft copolymer B present in an aqueous dispersion by means of a precipitant which is an aqueous solution of a mixture of MgSO4, Al2(SO4) and/or H2SO4, is described. The ABS molding compositions obtained have an improved yellowness index and high surface gloss.
