Abstract
A hydrophilic polymer blend is disclosed which comprises a first polymer component which is an organic solvent-soluble, thermoplastic polyvinylbutyral (PVB) and a second polymer component which is a hydrophilic poly(N-Vinyl lactam), e.g., a water soluble polyvinylpyrrolidone. The blend demonstrates slipperiness in aqueous environments and, among other applications, is useful in low-friction coatings for a wide variety of substrates. A method for providing the coatings is also described.
