The present invention provides resin materials for producing molded products endowed with excellent heat resistance, solvent resistance, toughness, tensile elongation, and transparency. Specifically, there are provided aromatic vinyl resin materials which have the following properties: Storage elasticity values G'(1.0) and G'(0.1) as measured at 300 DEG C, a strain gamma of 20%, and a frequency of 1.0 Hz or 0.1 Hz satisfy the expression, logÄG'(1.0)/G'(0.1)Ü ≤ 0.6, the heat of fusion DELTA H as measured over the range 200-295 DEG C is 8 to 50 (J/g), and the <1>H-NMR peak integrated values for the fraction corresponding to the temperature range of not lower than 50 DEG C, as collected from temperature rising election fraction on the Soxhlet extraction residue by use of cyclohexane or o-dichlorobenzene, satisfy the relation Ä1.8-2.1 (ppm)Ü/Ä1.0-1.7(ppm)Ü < 0.49. |
