| 摘要 |
A hydrophilic, lubricious, durable, flexible, coating comprising a crosslinked polyurea matrix complexed with a hydrophilic polymer selected from the group consisting of poly (ethylene oxide) and polyvinylpyrrolidone, said crosslinked polymer formed from the reaction of an isocyanate and a compound having at least two active hydrogens per molecule selected from the group consisting of polyamines, polymercaptans, and polycarboxylates or compounds with NH, NH2, SH or COOH groups on same molecule in the presence of said hydrophilic polymer, with the total sum of the average isocyanate functionality plus the average active hydrogen functionality exceeding 4 and the molar ratio of total NCO groups to total active hydrogens being at least 0.8.
