| titleOfInvention | Polyester resin and method for producing the same |
| abstract | PROBLEM TO BE SOLVED: To provide a polyester resin excellent in formability and a manufacturing method thereof while maintaining the transparency of a molded product while shortening the filling time in injection molding. SOLUTION: A polyester resin composed of a dicarboxylic acid component containing terephthalic acid as a main component and a diol component containing ethylene glycol as a main component, wherein the acetaldehyde content is 5 mass ppm or less, and the total dicarboxylic acid component The ratio of isophthalic acid to 1 to 3 mol%, the intrinsic viscosity IV satisfies the following formula (1), the haze of the molded plate having a thickness of 5 mm, which is injection-molded at a cylinder temperature of 280 ° C. and a mold temperature of 21 ° C., is 3 %, And the melt viscosity MV when extruded at a cylinder temperature of 290 ° C. and a shear rate of 600 sec-1 satisfies the following formula (2). Intrinsic viscosity 0.68 ≤ IV ≤ 0.77 dL / g (1) Melt viscosity MV ≤ 900 x IV-450 Pa · s (2) [Selection] None |
