摘要： A method for removing volatile materials, comprises adding a blowing aid to a polymer composition containing volatile materials, mixing them in a static mixing apparatus, and extruding the resultant mixture by an extruding apparatus into a devolatilizing tank, thereby the mixture is made to be blown, to cause removal of the volatile materials. First, the blowing aid (6) is discharged with an addition nozzle apparatus (2), in a direction opposite to the direction of the flow of the polymer composition (1), to be added, and the polymer composition is introduced into the static mixing apparatus (3), at a pressure at which the blowing does not take place, thereby mixing them. 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 is disclosed for the continuous production of an ABS resin. The polymerization step comprises at least two substeps, one being a first-stage substep of forming particles of the rubbery polymer and the other a second-stage substep of adjusting the particle sizes of the particles. The first-stage substep is conducted in a polymerization system making use of a plug flow reactor or a batch polymerization reactor, and conducts polymerization at least until the particles are formed in the polymerization mixture. The second-stage substep increases a converted amount of the monomer component into the polymer compared with that in the particle forming substep and makes the particles smaller. A polycarbonate-ABS resin composition is also disclosed.

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.

摘要： A process for the (co)polymerization of a monomer material, which includes at least an acrylonitrile monomer as an essential component, at a temperature of 80.degree. C. or higher by bulk or solution polymerization while allowing said monomer material to evaporate. The (co)polymerization is conducted while providing a vapor phase over a polymerization mixture in a reaction tank. During the (co)polymerization, the temperature of the vapor phase is maintained in a range of from 30.degree. C. to 65.degree. C. so that the polymerization is conducted without substantially releasing vapor, which is evaporated from the polymerization mixture, to outside of the reaction tank. By cooling the vapor phase of the reaction tank and maintaining its temperature in the above specific range in accordance with the present invention, it is possible to avoid mixing of a gelled polymer in a product and also to effectively remove reaction heat at the time of the (co)polymerization.
