TREATMENT OF POLYURETHANE SURFACES

摘要

The invention relates to an article having a polyurethane surface which has been rendered hydrophilic as well as to a method of rendering a polyurethane surface hydrophylic. According to the invention there is provided an article having a poyurethane surface provided with a coating of hydrophilic polyacrilamide or polymethacrylamide (other than poly(N-(mono hydroxy)propyl methacrylamide) bonded to the polyurethane by residues of a compound having a first functional group reactive with the polyurethane and a second functional group reactive with the polyacrylamide or polymethacrylamide.
