Title:
STYRENE RESIN COMPOSITION, BIAXIALLY STRETCHED STYRENE RESIN SHEET AND MOLDED BODY
Document Type and Number:
WIPO Patent Application WO/2017/029936
Kind Code:
A1
Abstract:
Provided are: a styrene resin composition which has improved impact strength and heat resistance without being deteriorated in transparency, thereby enabling the formation of a thinner product and having good secondary formability; a biaxially stretched styrene sheet which is obtained using this styrene resin composition; and a molded article of this biaxially stretched styrene sheet. Specifically provided are: a styrene resin composition which contains, as essential components, a styrene resin (A) having a structure derived from a styrene monomer (a1) and a structure derived from a methacrylic acid (a2), inorganic fine particles (B) having an average particle diameter of 0.1-10 μm and a rubber-modified polystyrene (C), and which is characterized in that the blending ratio of the inorganic fine particles (B) in the composition is within the range of 0.01-1.0% by mass; a biaxially stretched styrene sheet which is obtained using this styrene resin composition; and a molded article of this biaxially stretched styrene sheet.
