摘要：The prent invention relates to a process for producing a rubber reinforced styrene-bad resin, using a polymerization apparatus comprising: a prepolymerizer; mixing means and a circulating reactor connected with a circulation line; and a plug-flow type reactor, which process compris: continuously feeding a stock solution into the prepolymerizer; feeding the prepolymerized liquid into the mixer; in this mixer, mixing the prepolymer liquid with circulated liquid that is circulated from the circulating reactor at a flow amount of from 0.5 to 3 times (circulation flow ratio: volume ratio) the flow amount of the prepolymer liquid fed from prepolymerizer into the mixing means; particulating and dispersing the rubbery polymer in the mixed liquid by mechanical shear force; and then feeding the polymer liquid into the plug-flow type reactor, to thereby effect a polymerization. The production process of the prent invention makes it possible to produce, at a high speed, products of uniform qualities which are excellent in the balance among impact strength, appearance characteristics and coloring properties, without changing the mechanical shear force which controls the particle size.
