Method of manufacturing an aqueous dispersion

Abstract

A method of manufacturing an aqueous dispersion of a polymer comprises preparing an aqueous medium, the aqueous medium being an aqueous emulsion or suspension of a water-insoluble plasticiser, the aqueous medium including a dispersant; preparing a polymer melt; and combining the aqueous medium and the polymer melt to form the aqueous dispersion. By providing an aqueous medium comprising the combination of a water-insoluble plasticiser and a dispersant, it is made possible to prepare an aqueous dispersion of a polymer without the use of organic solvents and without pressurizing the aqueous medium or polymer melt. Also provided are a method of manufacturing a coated substrate using the aqueous dispersion; an aqueous dispersion of a polymer; and a use of an aqueous medium.
