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： An oil resistant rubber modified polystyrene composition comprises polybutadiene rubber particles having an average volume particle diameter of 6 to 13 &mgr;m dispersed in polystyrene. The oil resistant rubber modified polystyrene of the present invention has a gel content of 25 to 35% by weight, a degree of swelling of 13 to 22, a residual volatile content of 2000 ppm or less, and a total amount of dimer and trimer of 8000 ppm or less. The oil resistant rubber modified polystyrene composition may be prepared by polymerizing styrene in the presence of polybutadiene rubber, foaming a solution of the rubber modified polystyrene under a reduced pressure of 3 to 40 mm Hg, heating the solution in a tubular heater to a temperature of 190 to 230° C., and then flushing the heated solution into a gas-liquid separator to devolatilize an unreacted monomer and a solvent therefrom.

摘要： A method of dissolving a rubber continuously to form a raw material for the production of rubber-modified polymer, by dissolving a rubber in a monomer liquid dissolving the rubber and capable of reacting with the rubber in the presence or absence of a solvent. Pieces of rubber are fed continuously to a dissolution tank to allow the dissolved rubber and the undissolved rubber to coexist in the dissolution tank, wherein the concentration of the dissolved rubber is the concentration at which the feeding to the reactor is made, and the quantity of the undissolved rubber present in the dissolution tank is at most the quantity that prevents pieces of the undissolved rubber from sticking to one another to form larger rubber masses. The time required for dissolution can be shortened, and the size of a dissolution tank can be made smaller, compared with the conventional methods.
