PROBLEM TO BE SOLVED: To obtain an AS resin-based biaxially stretched sheet consisting of a styrene/acrylonitrile copolymer resin as a main material and formed from a polymer blend thereof with a polycaprolactone, and a thermally formed product therefrom. SOLUTION: This AS resin-based biaxially stretched sheet rich in transparency, oil resistance and thermally forming properties, is obtained by extruding a resin composition containing >=5wt.% acrylonitrile component, and consisting of a styrene/acrylonitrile copolymer resin having 0.5-30g/10min melt flow rate based on JISK7210 (test temperature; 230 deg.C, test load; 3.80kgf) and a polycaprolactone, and having a weight composition (expressed by percentages) of 95-60wt.% former to 5-40wt.% latter, and forming the sheet with biaxially stretching. |
