Document Type and Number:
Japanese Patent JP2023000623
Kind Code:
A
Abstract:
To provide a method for separating a function-applying layer from a thermoplastic resin molded body having the function-applying layer to simply recover the thermoplastic resin molded body.SOLUTION: A method for recovering a thermoplastic resin molded body separates a function-applying layer from the thermoplastic resin molded body by hydro-thermally treating the thermoplastic resin molded body having the function-applying layer under a pressure of 101 kPa or higher and under a temperature condition where a softening point of a thermoplastic polymer forming the thermoplastic resin molded body is ± 30°C.SELECTED DRAWING: None
