CA 2421942

Polymer composites comprising a water-insoluble polymer and a water-sensitive polymer are disclosed. The water-sensitive polymer is a copolymer polymerized from one or more alkylene oxide monomers and one or more epoxy-functional monomers. The polymer composites can be used in the manufacture of articles having enhanced lubricious-when-wet properties, e.g., wet-shaving devices, and medical devices, e.g., catheters. The articles can provide enhanced retention of lubricity after repeated uses.

L'invention concerne des composites polymériques comprenant un polymère hydro-insoluble et un polymère hydro-sensible. Le polymère hydro-sensible est un copolymère polymérisé à partir d'au moins un monomère d'oxyde d'alkylène et au moins un monomère à fonction époxy. Les composites polymériques peuvent être utilisés dans la fabrication d'articles possédant des propriétés lubrifiantes améliorées quand ils sont mouillés, par ex. des dispositifs pour le rasage mouillé, et des dispositifs médicaux, par ex. des cathéters. Ces articles peuvent présenter une conservation du pouvoir lubrifiant améliorée après des usages répétés.
