VERFAHREN ZUR DISPERSION VON FESTSTOFFTEILCHEN IN TEILCHENPOLYMEREN |
摘要 |
Process for dispersing solid particles in a particulate polymer, which comprises the steps of: (a) forming a solution (OS) of particles of a polymer (P1) in an organic solvent (S); (b) forming an aqueous dispersion (AD) of solid particles (P2); (c) mixing said solution (OS) with said dispersion (AD) as to obtain a liquid mixture (M), while avoiding substantial precipitation of either polymer (P1) or particles (P2); (d) mixing said liquid mixture (M) with a non solvent (NS) as to obtain a slurry (SL) comprising particles (P3); a phase transfer agent (PTA) being further present during steps (b), (c) and/or (d). |
