Beschreibung
Zusammenfassung:	The invention relates to new ethylene vinyl acetate-based polymer dispersions with increased stability compared to state-of-the-art and to a preparation process thereof. The invention also relates to a method for inhibiting wax deposition and reducing the pour point, viscosity and yield stress of crude oils by treating the crude oils with these stable ethylene vinyl acetate-based polymer dispersions.
