Abstract
A process for providing enzyme activity to the surface of an article is described, comprising forming a film on the surface of the article, said film comprising an acid anhydride group-containing polymer and a polyol, wherein the acid anhydride groups are partially reacted with the polyol, and thereafter reacting the unreacted acid anhydride groups with an enzyme. Such an article provided with enzyme activity on the surface can be used for the production of food, medicines, etc., and as a medical material.
Claims26
A process for providing enzyme activity to the surface of an article comprised of an organic polymeric material, comprising forming a film on the surface of the article, said film consisting essentially of an acid anhydride group-containing polymer selected from the group consisting of a maleic anhydride-styrene copolymer, a maleic anhydride-methyl vinyl ether copolymer, and a maleic anhydride-isobutylene copolymer and a polyol, wherein the acid anhydride groups are partially reacted with the polyol, and thereafter reacting the unreacted acid anhydridge group with a fibrinolytic enzyme selected from the group consisting of urokinase or streptokinase.
An article comprised of an organic polymeric material having enzyme activity on the surface thereof, said activity being provided by forming a film on the surface of the article, said film consisting essentially of an acid anhydride group-containing polymer selected from the group consisting of a maleic anhydride-styrene copolymer, a maleic anhydride-methyl vinyl ether copolymer, and a maleic anhydride-isobutylene copolymer and a polyol, wherein the acid anhydride groups are partially reacted with the polyol, and thereafter reacting the unreacted acid anhydride groups with a fibrinolytic enzyme selected from the group consisting of urokinase or streptokinase.
