Abstract:
1. A method for producing a thermoplastic polymer material, the method comprising the steps of: supplying component (A) below to a vent extruder comprising a starting material supply opening, a liquid inlet, and a vent via the starting material supply opening of the vent extruder; supplying component (B) below to the vent extruder via the liquid inlet of the vent extruder; melting and kneading component (A) and component (B) within the vent extruder; and degassing a volatile component via the vent extruder and extruding a die a thermoplastic polymer material comprising a thermoplastic polymer contained in component (A) and at least one compound group S contained in component (B); wherein component (A) is a polymer composition comprising a thermoplastic polymer and at least one of the group consisting of organic solvent and a monomer; wherein component (B) is a solution of at least one compound group S below; compound group S is selected from the group consisting of a compound represented by the formula C the alkoxylated material is a compound in which at least one hydroxy group of a compound represented by formula (1) below is alkoxylated with an alkyl group having 1 to 12 carbon atoms, and the compound represented by formula (1) being a compound comprising in the molecule an aldehyde or ketone group and m−1 hydroxy groups wherein m denotes an integer of not less than 3, wherein p denotes an integer of not less than 2.
