Polyester resin particle, and its manufacturing method |
| abstract |
Polyester resin particle which can suppress the fusion at the time of providing polyester prepolymer particle to heat processing, such as crystallization and solid state polycondensation, and can obtain a high transparency molded article by thermoforming, without reducing solid-state polycondensation speed | rate. To provide. The manufacturing method of the polyester resin which heat-processes and heat-processes the polyester prepolymer particle obtained by melt-polycondensing a dicarboxylic acid component and a diol component in this order. When the hydrothermal treatment is performed, polyester prepolymer particles having an intrinsic viscosity of 0.10 dL / g or more and 1.0 dL / g or less and a density of 1.36 g / cm 3 or less are higher than the glass transition temperature of the polyester prepolymer particles at 100 ° C. It is made to contact hot water of the temperature of less than the conditions on condition which satisfy | fills following formula (1).n n n 40 ≤ (T-Tg) t ≤ 6000 (1)n n n (Wherein t: hydrothermal treatment time (seconds), T: hydrothermal temperature (° C), Tg: glass transition temperature of polyester prepolymer particles (° C)) |
