Abstract
Abstract Fluorochemical copolymers, useful as wet-end papermaking additives which impart oil and water repellency and food stain resistance to ovenable paperboard under food cooking conditions, and as a treatment for imparting oil and water repellency to textile fibers. The fluorochemical copolymers are derived (by weight) from about 60 to 80% fluorochemical acrylate or halogenated alkyl or alkoxyalkyl acrylate, 2 to 30% alkyl or alkoxyalkyl acrylate or methacrylate, 2 to 15% glycidyl acrylate or methacrylate, 1 to 6% of certain cationic acrylates or methacrylates, and 0 to 20% vinylidene chloride.
