Abstract
A polymer is dissolved in a first liquid or the polymer is brought into the liquid phase. To the solution are added particles which are insoluble in the first liquid, so that a suspension or dispersion results. The suspension or dispersion is then transferred into an excess of second liquid, in which both the polymer and the particles are insoluble. The second liquid is mixed vigorously and this results in a precipitate of the polymer with the particles encapsulated therein.
