## Abstract

Waterborne acrylic
polymer dispersions are typically produced via
emulsion polymerization by using low molar mass surfactants. While
these surfactants ensure dispersion stability, they negatively affect
coating properties, such as water resistance, adhesion, haze formation,
and barrier performance. A promising alternative is polymeric surfactants.
Properly designed, polymeric surfactants prevent leaching and associated
issues while enhancing coating performance. This review begins by
explaining the use of polymeric surfactants, followed by an overview
of their types and the polymerization methods employedprimarily
bulk, solution, and emulsion polymerization. Then, polymeric surfactants
synthesized through emulsion polymerization will be described, and
their role in subsequent emulsion processes for waterborne binder
production will be discussed. Additionally, the review examines coating
morphology and presents examples of industrial applications, including
coatings for printing and packaging.
