Abstract (en)
[origin: WO2015197442A1] Described is a method for producing an ABS graft copolymer, comprising a step for isolating graft copolymer B in an aqueous dispersion by means of a precipitating agent that is an aqueous solution of a mixture of MgSO4, Al2(SO4) and/or H2SO4. The obtained ABS molding compounds have an improved yellowness index and high surface gloss.
