摘要： A coating composition for an article surface includes a uniform blend of an elastomeric segmented hydrophilic polyetherurethane and a hydrophilic polymer, such as polyvinylpyrrolidone. The invention includes a method for rendering an article surface lubricious which includes coating the composition onto the article surface and contacting the coated surface with an aqueous liquid.

摘要： An article which becomes lubricious when wet includes a base polymer and a coating composition thereon. The composition includes a lubricating polymer and a matrix polymer which adheres to the base polymer and serves as a carrier for the lubricating polymer. The composition may also include a homogenizing polymer to enhance the compatibility of the matrix and lubricating polymer. The invention includes a method to make the article of the invention by coextruding the base polymer and the coating composition.

摘要： A composition which includes polyvinylpyrrolidone and a polyurethane is melt processed to give a shaped article. The melt processing may be a coextrusion with a substrate polymer to give a shaped article having the composition coated on the surface thereof. The article surface is lubricious when contacted with water.
