Abstract: PURPOSE:To provide a complex type membrane capable of being prepared from laminated low-strength thin membranes and useful as dyalysis membrane for artificial kidney system, ultrafiltration membrane, or oxygen exchange membrane for membrane-type artificial lung system. CONSTITUTION:A foamed material having continuous pores such as one based on polyurethane, polystyrene, cellulose acetate, phenol, silicone, urea melamine is laminated with a semipermeable membrane such as cellulose acetate, ethyl cellulose, polyvinyl alcohol, etc. This membrane is prepared by solvent casting method so that a little solvent such as water, methanol, etc. remains in the formed semipermeable membrane, and in this condition, the foamed material is bonded by contacting.

Abstract: PURPOSE:A copolymer excellent in hydrophilicity, antithrombotic property and mass permeability and useful as a medical material such as a catheter or a stainproofing, antifogging coating material, prepared by grafting a monomer containing a polyethylene oxide chain onto a vinyl chloride copolymer. CONSTITUTION:In the presence of a copolymer (A) consisting of above 10wt% vinyl chloride and below 90wt% other copolymerizable monomers (e.g., vinyl acetate), polyethylene glycol mono-acrylate or methacrylate (B) is graft-polymerized with the aid of a catalyst (e.g., benzoyl peroxide) to obtain a graft copolymer, specific viscosity >=0.2, consisting of below 95wt% copolymer A component and above 5wt% graft component of the formula, wherein R1 is H or CH3, R2 is H, CH3 or C2H5 and n is an integer >=5. USE:Electrophoretic or liquid-chromatographic carrier, food packaging material, selectively permeable membrane.
