Abstract (en)

[origin: WO9960051A2] Novel manufactures are provided having surfaces which upon contact with water promptly provide for high and permanent lubricity. The surfaces involve a carboxylic acid functionality which at least in part is present as an ester and/or amide and/or salt. Various polymers are used with a wide variety of solid polymeric carriers. The surfaces may be achieved by applying a solution onto the carrier and then heating, by coextrusion of the coating and the carrier or by contacting the carrier with the polymer.
