ABSTRACT:
A process for producing an antithrombogenic vinyl acetate polymer or a hydrolyzate thereof which comprises treating the vinyl acetate polymer or hydrolyzate with a solution of a fibrinolytic enzyme so as to fix the fibrinolytic enzyme to the polymer. The resulting antithrombogenic vinyl acetate polymer or hydrolyzate is advantageously used in a material which comes into contact with the blood in use and is especially useful in a surgical tube.
