    摘要: A modified hollow-fiber membrane which has improved surface hydrophilicity without increasing the amount of components released therefrom, is less apt to interact with living-body components, does not adsorb proteins, and is less apt to deteriorate in performance. The hollow-fiber membrane has a copolymer of 2-methacryloyloxyethylphosphorylcholine and other polymerizable vinyl monomer held on a surface of the membrane, the copolymer being present on the surface in a higher concentration than in other parts of the membrane. The modified hollow-fiber membrane is useful in medical applications such as hemodialysis and blood filtration and in the medical industry, food industry etc.

The emulsion forms a film on an adherend to decrease the infiltration into the adherend, exhibits an adhesion force to a hydroxyapatite structure, a cement, a metal or a mineral when it is applied thereto to form a film by only drying around room temperature without washing it with water, and exhibits excellent affinity to a radical-polymerizable acrylic resin composition.

    摘要: A method for making a biocompatible medical article, and preferably, a blood compatible medical article, through the use of a copolymer coating. The copolymer coating is synthesized using methacrylate or acrylate monomers with a functional group (primary amino group) for subsequent attachment of heparin. Synthesis of the copolymer coating is carried out using the proper proportion of hydrophobic monomer/hydrophilic monomer/functional monomer in order to optimize the solubility of the copolymer in alcohol, its insolubility in water (before and after heparin coupling), the heparin coupling efficacy and heparin bioactivity. Once the copolymer coating is fashioned, a medical article is coated with it. The coating is thereafter dried and heparin attached. In such a manner the present invention provides for a method for making a biocompatible medical article, and preferably, a blood compatible medical article.
