Abstract

The invention relates to preparations comprising a wax in which polymer particles are present, where the polymer particles comprise at least one effect substance, obtainable by, by means of a miniemulsion polymerization carried out in the presence of a wax-immiscible solvent, distributing at least one effect substance in polymer particles, and incorporating the polymer particle dispersion obtained in this way into a wax by phase transfer.Furthermore, the invention relates to compositions comprising a polymeric matrix in which, in essentially homogeneous distribution, the aforementioned polymer particles are present, obtainable by incorporating the aforementioned polymer-particle-comprising wax as preparation into a polymeric matrix.
