A process for coating of surfaces with hydrogels and a resistance to yellow layer, which is provided with a hydrophobic polymer substrates

摘要

The present invention relates to a process for coating of surfaces with hydrogels, comprising the steps of dollars a applying a composition comprising at least - forming a hydrogel polymer, on a surface and dollars a formation of a hydrogel - coating on the surface, dollar a wherein - the hydrogel polymer which forms by a thermal treatment under inert gas at a temperature in the range of from 50 to 180 deg c and a pressure greater of 1 bar on the surface is immobilized. Dollars a of the further, the present invention relates to polymer substrates, the one with the process of the present invention have available of lubricious hydrogel.
