Abstract
A hydrophilic polymer blend is disclosed which comprises a first polymer component which is an organic solvent-soluble, thermoplastic polyurethane and a second polymer component which is a hydrophilic poly(N-vinyl lactam), e.g., a water soluble polyvinylpyrrolidone. The blend demonstrates slipperiness is aqueous environments and, among other applications, is useful in low-friction coatings for a wide variety of substrates.
Claims20
A stable hydrophilic polymer blend which consists essentially of a first polymer component which is an organic solvent-soluble, preformed, thermoplastic polyurethane having no reactive isocynate groups and a second polymer component which is a hydrophilic poly (N-vinyl lactam), said blend capable of withstanding exposure to water without significant loss of said hydrophilic poly (N-vinyl lactam).
