Title
(EN) STYRENE RESIN COMPOSITION SHEET AND MOLDED ARTICLE
(FR) FEUILLE DE COMPOSITION DE RÉSINE STYRÉNIQUE ET ARTICLE MOULÉ
(JA) スチレン系樹脂組成物シート及び成形体
Abstract
(EN)
Provided is a sheet obtained from a resin composition having an excellent balance of gloss, oil resistance, and sheet strength. This styrene resin composition sheet is obtained from a styrene resin composition including (A) a styrene resin and (B) a polyester resin, and is characterized in that in the infrared absorption spectrum measured by an ATR-FTIR method, the ratio (α/β) of the absorbance ratio (α) at 1750 cm-1 and 698 cm-1 in the outermost surface and the absorbance ratio (β) at 1750 cm-1 and 698 cm-1 in the sheet interior is 2 to 10.
(FR)
L'invention concerne une feuille obtenue à partir d'une composition de résine présentant un excellent équilibre de brillance, de résistance à l'huile et de résistance de feuille. Cette feuille de composition de résine styrénique est obtenue à partir d'une composition de résine styrénique comprenant (A) une résine styrénique et (B) une résine de polyester et est caractérisée en ce que, dans le spectre d'absorption infrarouge mesuré par un procédé ATR-FTIR, le rapport (α/β) du rapport d'absorbance (α) à 1750 cm-1 et 698 cm-1 dans la surface la plus à l'extérieur et le rapport d'absorbance (β) à 1750 cm-1 et 698 cm-1 dans l'intérieur de la feuille est de 2 à 10.
(JA)
光沢、耐油性とシート強度のバランスに優れた樹脂組成物から得られるシートを提供する。 本発明のスチレン系樹脂組成物シートは、(A)スチレン系樹脂と(B)ポリエステル系樹脂とを含むスチレン系樹脂組成物から得られるシートであって、ATR-FTIR法により測定される赤外吸収スペクトルにおいて、最表面における1750cm-1及び698cm-1での吸光度比(α)と、シート内部における1750cm-1及び698cm-1での吸光度比(β)と、の比(α/β)が、2以上10以下であることを特徴とする。
