Title:
METHOD FOR PRODUCING THERMOPLASTIC RESIN COMPOSITION
Document Type and Number:
Japanese Patent JP2019172865
Kind Code:
A
Abstract:
To provide a method for producing thermoplastic resin composition in which the scattering of additives to outside of solid phase polymerization tank due to pressure reduction during solid phase polymerization can be prevented, and the generation of discolored composition can be suppressed.SOLUTION: Provided is a method for producing thermoplastic resin composition, which is a method for producing thermoplastic resin composition in which one or a plurality of additives are added during solid phase polymerization of a thermoplastic resin using a rotary batch type solid phase polymerization apparatus under reduced pressure, and in which the shape of the additive is flake shape and the melting point of at least one additive is below the solid phase polymerization temperature.SELECTED DRAWING: Figure 1
