    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 colored styrenic resin composition comprises 100 parts by weight of a styrenic resin, 0.1 to 5 parts by weight of titanium oxide and 0.05 to 2.5 parts by weight of an organo-tin compound and in which the amount of the organo-tin compound is not less than 10% by weight on the basis of the amount of the titanium oxide. The resin composition ensures the production of injection-molded articles free of black streaks and, therefore, the articles formed from the resin composition of the invention have high commercial value. The colored styrenic resin composition is useful as a material for the production of housings of, for example, a variety of electric appliances and office machinery and equipment as well as miscellaneous goods.

Rubber particles located at a depth of 0.5-1.5 .mu.m from a surface of the molding morphologically comprise at least the following two types of particles:(1) A particles having an a/b ratio not greater than 1.5, wherein a and b represent a major axis and a minor axis, respectively, and(2) B particles having an a/b ratio not smaller than 5, wherein a and b have the same meanings as defined abovewhen a section extending at the depth in parallel with the surface of the molding is observed in an electron micrograph taken by the ultrathin sectioning technique. Assuming that the total area of the rubber particles as observed in the electron micrograph is 100%, the total area of the A particles accounts for at least 10% and that of the B particles is in a range of 0.01-90%.

    摘要： A styrene resin is disclosed having excellent moldability and physical properties and is suited for recycling; and a thermoplastic polycarbonate composition with the styrene resin. The styrene resin contains 50 to 90 wt. % of a continuous phase component (S) composed of a copolymer of a styrene monomer, an unsaturated nitrile monomer; and 10 to 50 wt. % of a dispersed phase component on which said monomers have been grafted and which has occluded said copolymer. In the styrene resin, no triple chain unit AAA is detected from the unsaturated nitrite monomer component (A) in the continuous phase component (S) and a double chain unit AA amounts to 3% or less based on the whole units (A) detected.
