    摘要： A modified styrene-based resin composition in which silicone powder is added to styrene-based resin.One can obtain styrene-based resin compositions remarkably improved in impact resistance and sliding properties, particularly in permanence during sliding. In particular, when the base material is transparent polystyrene-based resin, it was found that the present invention can provide styrene-based resin compositions having excellent impact strength, sliding properties, and transparency without spoiling their fluidity and thermostability. In addition, use of rubber modified polystyrene as styrene-based resin permits styrene-based resin compositions exhibiting well-balanced impact resistance, sliding properties, heat distortion resistance, molding properties, workability, and surface appearance of molded articles. Thus, the present invention enables general-purpose styrene-based rigid thermoplastics to be used for various applications, that is, it allows improvement of such thermoplastics particularly in adaptability to injection molding, extrusion molding and the like, and thereby will contributes to extension of the range of their application.
