A resin composition is provided. The resin composition includes a styrene-acrylonitrile based copolymer of 75 parts by weight to 90 parts by weight and rubber particles of 10 parts by weight to 25 parts by weight. The resin composition includes an oligomer trimer. The oligomer trimer includes at least one monomer unit selected from the group consisting of a styrene based monomer unit and an acrylonitrile based monomer unit. Wherein, a residual acrylonitrile based monomer is less than 5 ppm of the total weight of the resin composition. The ratio of the peak area of acetophenone to the peak area of air for the resin composition as analyzed by a thermal desorption gas chromatography mass spectrometer (TD-GC-MS) is 100 to 300.

The present invention relates to a thermoplastic styrenic resin composition comprises a styrenic copolymer comprising 15-100 parts by weight of a unit derived from a styrenic monomer (i-1), 0-45 parts by weight of a unit derived from a vinyl cyanide monomer (i-2), 0-40 parts by weight of a unit derived from a copolymerizable vinyl monomer (i-3) other than the above monomers, and 0.0005-1.0 parts by weight of a unit derived from a polyfunctional maleimide monomer, all based on 100 parts by weight of the total amount of (i-1) to (i-3). The thermoplastic styrenic resin composition manufactured in the present invention is excellent in processability. The rubber modified thermoplastic styrenic resin composition of the present invention gives a good heat stability, impact strength, fluidity and other mechanical properties. In addition, it also gives a uniform wall thickness, and the gloss on the surface of injected products after painting process is excellent. The thermoplastic styrenic resin composition and the rubber modified thermoplastic styrenic resin composition in this invention are applicable for electric and electronic articles and they are especially applicable for the forming and processing of refrigerator plates. So, the thermoplastic styrenic resin composition and the rubber modified thermoplastic styrenic resin composition of the present invention is beneficial to the industry is also commercially valuable.

Thermoplastic styrenic resin composition

Disclosed is a method for producing a flame retardant polycarbonate resin composition by using a screw extruder, which comprises extruding a resin component (mainly comprising a polycarbonate) and an organic phosphorus compound having an acid value of not more than 0.1 mg KOH/g while kneading, wherein the temperature of the resin component in the extruder is not higher than 300&deg; C., and the residence time of the resin component in the extruder is not more than 40 seconds.
