ABSTRACT:
A non-ionic graft copolymer has a hydrophobic backbone and non-ionic, hydrophilic side chains having a molecular weight of at least 500, preferably 100–2000 is substantially insoluble in water, but soluble in an aqueous vehicle, and is particularly suited for use in aqueous coating compositions in which water comprises no more than 80% by weight of the vehicle for the composition.
