Abstract

PURPOSE: To produce a hydrogel membrane which is excellent in strength, etc., and is useful as a wound-protecting membrane or a material for delaying medicament release, by heat-treating a membraneous material containing an epoxy group- containing vinylpyrrolidone copolymer and polyurethane and then, subjecting the membraneous material to hydration treatment.
CONSTITUTION: A cylindrical or flat plate substrate is immersed into an organc solvent solution prepared by dissolving 80W10wt% of an epoxy group-containing vinylpyrrolidone copolymer and 20W90wt% of polyurethane having a tensile strength of at least 50kg/cm2 and an elongation at break of at least 100%, and is dried, after withdrawal, at 40W80°C in an inert gas thereby to form a membraneous material. Then, the membraneous material is heat-treated in vacuum or in an inert gas, at 100W180°C and subjected further to hydration treatment. Said epoxy group-containing vinylpyrrolidone copolymer is prepared by copolymerizing 1W20mol% of a vinyl monomer having, in the molecule, a carbon to carbon double bond and an epoxy group, such as glycidyl methacrylate with 99W80mol% of polyvinylpyrrolidone at a temperature of below 60°C in an inert solvent.
