PCT No. PCT/SE85/00376 Sec. 371 Date May 9, 1986 Sec. 102(e) Date May 9, 1986 PCT Filed Sep. 27, 1985 PCT Pub. No. WO86/02087 PCT Pub. Date Apr. 10, 1986.A surface coated article comprising a substrate with a cured polyethylene oxide-based coating thereupon. The essential features of the article are that the coating essentially consists of polyethylene oxide chains, with one free end and one end that has been cross-linked to other chains via a special cross-linking agent, that the cross-linking has been performed by radiation, and that the substrate has been swollen prior to cross-linking. The article can be prepared by applying to the substrate a solution containing the polyethylene oxide, the cross-linking agent, a swelling solvent and optionally a radical initiator, evaporating the solvent and cross-linking the coating by radiation curing. A suitable coating composition comprises per mole of the polyethylene oxide, 0.1-10 moles of the cross-linking agent, 0-500 moles of the solvent and optionally 0.0001-0.5 moles of the radical initiator. The article is especially useful within the biomedical field. |
