    摘要： A method of producing ABS moulding compositions wherein a solution of polymers in group (A) solvents is gradually supplied to a polymerizing mixture of previously-formed soluble rubber, aromatic mono-alkenyl compounds, ethylenically unsaturated nitrites, optional other copolymerizable compounds and optionally a group (B) solvent or a mixture of group (A) and group (B) solvents, the gradual addition of the polymer solution to the polymerizing mixture being started before the beginning of phase inversion and at a monomer conversion rate of 5 to 15% and a viscosity of the polymerizing mixture of less than 20 Pa.sec with simultaneous continuation of polymerization, the group (A) solvent is an aliphatic (C.sub.1 -C.sub.8) or cycloaliphatic alcohol, ketone, ether, ester and/or nitrile, and the group (B) solvent is an aliphatic (C.sub.4 -C.sub.10), cycloaliphatic and/or aromatic hydrocarbon.
