Heat-resistant styrene resin composition, non-foam extruded sheet, foam extruded sheet, and molded articles thereof.

摘要

PROBLEM TO BE SOLVED: To solve a problem of a heat-resistant styrene resin composition having excellent appearance, heat resistance, mechanical strength, and reworkability with respect to a styrene resin, and a non-foam extruded sheet, a foam extruded sheet, and molding using the same. To provide goods. SOLUTION: 100 parts by mass of a heat-resistant styrene resin (a) having a styrene-based monomer unit, a (meth) acrylic acid monomer unit, and an α-methylstyrene monomer unit, and 16 or more carbon atoms. The monovalent alcohol (b) contains 0.03 to 1.0 parts by mass, and the heat-resistant styrene resin (a) contains the styrene-based monomer unit and the (meth) acrylic acid monomer unit. And when the total content of the α-methylstyrene monomer unit is 100% by mass, the content of the styrene monomer unit is 61 to 95% by mass, and the (meth) acrylic acid monomer is used. A heat-resistant styrene-based resin composition, wherein the content of the unit is 1 to 5% by mass, and the content of the α-methylstyrene monomer unit is 4 to 35% by mass. [Selection diagram] None
