Document Type and Number:
WIPO Patent Application WO/2024/014397
Kind Code:
A1
Abstract:
The present invention provides: a production method that is for a thermoplastic resin composition in which solid content is appropriately pulverized, and that performs a high level of pulverization simultaneously with kneading, while omitting the workload of filtering and a separate pulverization step; and a kneader used in the production method. Provided are: a production method for a thermoplastic resin composition, wherein a thermoplastic resin raw material and solid content having an average particle size of not less than 50 μm are supplied to a kneading device kneader which has at least one screw (103, 104) and a casing (105) that accommodates the screw; and a kneader used in the production method. The production method is characterized by comprising a kneading/pulverizing step for kneading the thermoplastic resin composition containing the solid content while pulverizing the solid content, wherein a region of clearance (C1-C3) of not more than 500 μm is formed in the kneading device kneader by the screw.
