Abstract
Polymer latex binders useful for preparing coating compositions containing low levels of, or which are substantially free of, volatile organic compounds (VOCs) such as volatile freeze-thaw additives are prepared by multistage emulsion polymerization, wherein one stage provides a copolymer having a relatively high glass transition temperature and containing an oxyalkylene-containing (meth)acrylate comonomer.
