Then, using the extruding apparatus (11), the resultant mixture is extruded into the devolatilizing tank (4), so that the polymer is made into a blown product at such a temperature and a pressure that the blowing coefficient B is 1.4 or more, thereby causing the removal of volatile materials.B=A'/A Expression (1)wherein A represents the cross-sectional area of an extruding apparatus, and A' represents the average cross-sectional area of the polymer composition in a direction perpendicular to the vertical direction of the blown polymer composition, at a point where the polymer composition is dropped from the lower part of an opening section of the extruding apparatus vertically 50 cm to 1 m. The method can give a polymer composition having residual volatile materials in very small amounts, by removing volatile materials continuously with high efficiency.

    摘要: A process for preparing rubber modified high impact resins by dissolving a rubbery polymer in a monomer containing an aromatic vinyl monomer or a mixture of an aromatic vinyl monomer and a vinyl cyanide monomer followed by polymerizing the monomer, the two steps being carried out in at least two polymerization reactors with a particle disperser placed between the first and second reactors. High impact resins having excellent surface properties are obtained with a savings in a power consumption by controlling:(1) the relationship between the concentration of the polymerized monomer and the content of the rubbery polymer in the first reactor;(2) the relationship between the volume occupied by the polymerizing liquid in the first reactor and the inner volume of the particle disperser; and(3) the peripheral linear velocity of a shearing stirrer in the particle disperser.
