    摘要: Aqueous-dispersed polymer compositions are prepared comprising polymerized therein (a) monovinylidene aromatic monomer (e.g., styrene), (b) acyclic conjugated diene monomer (e.g., butadiene), and (c) ethylenically unsaturated carboxylic acid monomer(s) (e.g. acrylic and or fumaric acid) and are further benefited by polymerizing therein (d) a cyanoalkyl ester of an ethylenically unsaturated carboxylic acid. The aqueous-dispersed polymers can also comprise polymerized therein an ethylenically unsaturated nitrile monomer such as acrylonitrile. The use of the cyanoalkyl ester, such as 2-cyanoethylmethacrylate (2-CEMA), results in latex polymers with improved performance in paper coating formulations. In particular, paper coatings can be prepared which have improved performance (i.e., wet and dry pick resistance) in offset printing applications.
