Abstract
A treatment of a shaped flexible elastomer item so as to form a coating of a hydrophilic polymer on the surface of the elastomer. The treatment encompasses cleaning of the elastomer surface, immersion of the elastomer in a concentrated solution of a strong acid such as sulphuric acid, washing, and subsequent dipping of the treated elastomer in a solution of an uncured hydrophilic polymer. The treated elastomer is then held at an elevated temperature for a period of time to cure the polymer coating and to bond the polymer coating to the elastomer.
