Abstract
Abstract Mixtures of (1) a polymer of at least one polyfluoroalkyl acrylate or methacrylate and (2) a copolymer of (a) at least one polyfluoroalkyl acrylate or methacrylate, (b) at least one 3-chloro- (or 3-bromo-) 2-hydroxypropyl acrylate or methacrylate, (c) at least one alkyl acrylate or methacrylate and (d) at least one polyoxyethylene acrylate or methacrylate. Mixtures are prepared by first polymerizing (1) and then (2) (a)-(d). Mixtures are useful as oil- and water-repellents, particularly for rainwear.
