Abstract
A process for modifying the surface of a preformed polymeric substrate to impart lubricity and other desired properties thereto, without at the same time significantly altering the bulk properties of the substrate, by epoxidizing the substrate's surface and reacting the epoxide groups so formed with a fluorocarbon capable of cleaving the epoxide rings and covalently bonding thereto. The article so formed is also disclosed.
