摘要:
An aqueous coating composition is provided that is preferably substantially free of styrene and structural units derived from styrene. The coating composition includes a resin system that preferably includes a water-dispersible polymer and an emulsion polymerized ethylenically unsaturated monomer component. The resin system is preferably formed using a process that includes emulsion polymerizing the ethylenically unsaturated monomer component in the presence of an aqueous dispersion including the water-dispersible polymer. In certain preferred embodiments, the water-dispersible polymer is a salt of an acid- or anhydride-functional aromatic polyether polymer.
