Abstract

A process for making an aqueous emulsion of self-emulsifiable polyolefin employs a high molecular weight functionalized polyolefin and a hydrophilic polymer. The aqueous emulsion can be used to prepare a hybrid polyolefin-polyurethane dispersion useful, inter alia, as an adhesion-promoting coating for polymers such as the polyolefins.
