Abstract (en)
[origin: WO2009103681A1] The invention relates to a method for producing solid materials on the basis of synthetic polymers and biopolymers (A) by: (1) the solubilisation of (A) or of (A) and an additive (B) in a non-aqueous chaotropic liquid (C), (2) contacting of the solution or dispersion obtained (AC) or (ABC) with a liquid (D1), which is miscible with (C), in which however (A) is insoluble, to produce a phase (E) containing (A), (C) and (D1) and optionally (B) and a liquid phase (F) containing (C) and (D1), (3) optional separation of (E) from (F), (4) removal of (C) from (E) with the aid of (D1), to produce a gel (G) on the basis of (A), (5) impregnation of (G) with a liquid (D2) which is miscible with (C) and (D1) and in which at least (A) is insoluble and has a higher volatility than (D1), and (6) removal of (D1) and (D2) from (G) by evaporation. The invention also relates to the use of said materials.
