To solve problems such as a problem that it has been difficult to uniformly mix a resin with powder due to difference between the specific gravity of the resin and the specific gravity of the powder, when the resin and the powder are mixed each other and then formed into films or molded into a molded article, and a problem that it has also been difficult to uniformly mix a resin with powder, when the resin and a material having different specific gravity are generally united with a kneader to produce a master match.
The present invention provides a method for simply uniting a thermoplastic resin with a functional material. The uniting process can be performed without needing a resin-curing or liquidizing process and can process the resin in a powdery shape to a small stone-like suitable shape which can easily be used for post processes using twin-screw extruders. A method for producing the particles is characterized by uniting a functional material with a thermoplastic resin whose surface is at least softened or melted, to produce the united particles.
