    Abstract: Provided is a separation membrane module suffering from little sticking of organic matters, proteins, platelets and so on. A separation membrane which is a membrane comprising a polymer, characterized in that a functional layer is formed on the surface in one side of the membrane, the peak area percentage of carbon derived from ester group measured by the electron spectroscopy for chemical analysis (ESCA) on the surface of the preceding functional layer is 0.1% (by atomic number) or more but not more than 10 (% by atomic number), and the peak area percentage of carbon derived from ester group measured by the electron spectroscopy for chemical analysis (ESCA) on the surface opposite to the functional layer is not more than 10 (% by atomic number); and a separation membrane module provided with the same as a built-in membrane.

    Abstract: The present invention is characterized in that a base material comprises ester groups in the main chain and/or in the side chain(s), and comprises a polymer having hydrophobic groups. Particularly, the hydrophobic groups can be introduced by irradiating the base material with a radiation during the base material contacts an aqueous solution of a monohydric alcohol or an aqueous solution of an alcohol having not less than 2 hydroxyl groups, which is a monomer or a polymer, and which has one or more carbon atoms between the carbon atoms to each of which the hydroxyl group is bound in the monomer or in each monomer constituting the polymer.

    Abstract: In order to prevent a protein or peptide from adsorbing on a resin molding, the resin molding is brought into contact with an aqueous solution of a nonionic surfactant, and then the resin molding is irradiated with radiation rays and also a concentration of the surfactant in the aqueous solution is made to be 0.05 times to 500 times a critical micelle concentration of the surfactant at 25°C.

    Abstract: A hydrophilic material comprising a copolymer composed of a monomer (A) having a polyalkylene oxide unit and a polymerizable carbon-carbon double bond in its molecule, a methacrylate or acrylate monomer (B) and another monomer (C) having a polymerizable carbon-carbon double bond in its molecule, which material is characterized by containing the monomer (C) in the proportion of 10 to 90 % by weight. The invention provides a hydrophilic material which is soluble, readily moldable, and excellent in antithrombotic and antifouling properties, and further provides an antithrombotic material and a semipermeable membrane. These materials can be appropriately used in the medical field and as water-absorbent and antifouling materials.
