Abstract (en)
[origin: WO2011032907A1] The invention relates to formulations comprising preparations of active substances of low solubility in water in a polymer matrix of polyether copolymers, wherein the polyether copolymers are obtained by radically initiated polymerization of a mixture of 30 to 80% by weight of N-vinyl lactam, 10 to 50% by weight of vinyl acetate, and 10 to 50% by weight of a polyether, and of at least one surfactant in which the active substance of low solubility in water is amorphously present in the polymer matrix.
