Beschreibung
Zusammenfassung:	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. 本发明提供了不含苯乙烯的共聚物和含有该共聚物的涂料组合物。具体地，本发明提供了一种水性涂料组合物，其优选基本上不含苯乙烯和衍生自苯乙烯的结构单元。涂料组合物包含树脂体系，该树脂体系优选包含水分散性聚合物和乳液聚合的烯属不饱和单体组分。树脂体系优选使用包括在包含水分散性聚合物的水分散体存在下乳液聚合烯属不饱和单体组分的方法而形成。在某些优选的实施方式中，水分散性聚合物是酸或酸酐官能的芳族聚醚聚合物的盐。
