Abstract

A process for the manufacture of a polymer dispersion from a mixture of a first polypropylene polymer having sufficient carboxylic acid and/or carboxylic acid anhydride groups equivalent to an acid value of from 2 to 50 mg KOH/g nv polymer and a second polymer having a molar excess of functional groups capable of reacting with the carboxylic acid and/or carboxylic acid anhydride groups of the polypropylene is provided. Also provided herein are polypropylene dispersions in organic carrier liquid prepared by such method, as well as coating compositions comprising the dispersion and articles coated with the coating composition.
