PRODUCTION METHOD FOR A CRYSTALLINE THERMOPLASTIC RESIN COMPOSITION, MANUFACTURING METHOD FOR AN ELECTROPHOTOGRAPHIC MEMBER, AND MANUFACTURING METHOD FOR AN ELECTROPHOTOGRAPHIC BELT

摘要

Provided is a production method for a crystalline thermoplastic resin composition containing dispersed fine particles. The production method includes a step of dispersing fine particles in a crystalline thermoplastic resin while disintegrating agglomerated fine particles by shearing a resin kneaded product that contains the crystalline thermoplastic resin and the agglomerated fine particles and is free of a solvent as a main component. The step includes applying a stress to the resin kneaded product at a temperature that is equal to or more than a Tg of the crystalline thermoplastic resin, and is less than a Tm of the crystalline thermoplastic resin in such a manner that a tan δ of the resin kneaded product at the temperature becomes more than 1.

1. A production method for a crystalline thermoplastic resin composition containing dispersed fine particles,
the production method comprising a step of dispersing fine particles in a crystalline thermoplastic resin while disintegrating agglomerated fine particles by shearing a resin kneaded product that contains the crystalline thermoplastic resin and the agglomerated fine particles and is free of a solvent as a main component, wherein the step comprises an applying step in which a stress is applied to the resin kneaded product at a temperature that is equal to or more than a glass transition temperature of the crystalline thermoplastic resin, and is less than a melting point of the crystalline thermoplastic resin in such a manner that a loss tangent of the resin kneaded product at the predetermined temperature becomes more than 1.
