<P>PROBLEM TO BE SOLVED: To provide a manufacturing method in which a mechanical physical property of a thermoplastic polymer material is maintained even if the rotational number of a screw of an extruder is increased or a temperature of the polymer in the extruder is made high in the method for manufacturing the thermoplastic polymer material having a small amount of a volatile component by removing the volatile component from the thermoplastic polymer containing a solvent and/or a monomer by the vent type extruder. <P>SOLUTION: In the manufacturing method for the thermoplastic polymer material, the thermoplastic polymer material containing the thermoplastic polymer of component (A) and a compound of component (B) are extruded from a die by feeding the following component (A) from a material feeding port of the vent type extruder and feeding the following component (B) from a liquid pouring port of the vent type extruder. (A): the polymer composition containing the thermoplastic polymer and the organic solvent and/or the monomer. (B): a solution of at least one kind of compound selected from the group of compounds S consisting of trehalose, sucrose, lactose and maltose. <P>COPYRIGHT: (C)2012,JPO&INPIT |
