<p>A slippery material for medical use consists of a base component (A) to the surface of which is bound by strong covalent bonds a hydrophilic polymer (B). (A) is pref. a reactive polymer contg. alkali metal alcoholate, alkali metal amide, carboxylic, sulphonic, magnesium halide, fluoroborate or (pref.) amino gps. (B) is a hydrophilic polymer derived from a monomer contg. ethylene sulphide, propylene oxide, propylene sulphide, cyclooxabutane, 3 or 4-membered ring lactone or lactam, amino acid N-carboxylic anhydride, oxazolidine, ethylene imine, propylene imine, cyclic ether, cyclic azaether, cyclic thioether or (pref.) ethylene oxide gps.; pref. copolymerised with (meth)acrylamide, N-vinylpyrrolidone, monomethoxytriethylene glycol mono(meth)acrylate, etc. The proportion of reactive gps. (by wt.) in (A) is pref. 0.1-50%, and in (B) is pref. 0.01-50%.</p> |
