    Abstract: In a continuous bulk or solution polymerization process for producing rubber modified high-impact resins which comprises continuously feeding a raw material solution comprising a mixture of an aromatic vinyl monomer and a vinyl cyanide monomer and a rubber component dissolved in the mixture, together with a radical polymerization initiator, to a first reactor, polymerizing the raw material solution under high-shear agitation to a conversion required to transform the rubber component phase into dispersed particles, withdrawing the reaction mixture continuously from the first reactor at a rate corresponding to the feed rate of the raw material solution, and feeding the reaction mixture to a second or more reactors for further polymerization, rubber modified high-impact resins exhibiting excellent chemical resistance, thermal resistance and rigidity and having a good surface gloss can be produced by properly determining the weight ratio of the aromatic vinyl monomer to the vinyl cyanide monomer present in the raw material solution, the content of the rubber component in the raw material solution, the content of the solvent in the raw material solution, the property of the rubber component, the property of the radical polymerization initiator and the amount of initiator used, as well as the conversion of the monomers at the first reactor.

    Abstract: In a process for preparing rubber modified high impact resins (HI-PS and ABS) by polymerizing a starting monomer containing an aromatic vinyl monomer or a mixture of an aromatic vinyl monomer and a vinyl cyanide monomer and added with a rubber-like polymer and by using at least two polymerization reactors and a particle disperser placed between the both reactor, the process obtaining the resins of high grade by specifying the relationships between the concentration of the polymerized monomer in the first reactor and the content of the rubber-like polymer in the first reactor and between the volume occupied by the polyemrizing liquid in the first reactor and the inner volume of the particle disperser, and the peripheral linear velocity of a shearing stirrer in the particle disperser.
