Abstract

Abstract An antithrombic resin composition comprising is disclosed which comprises synthetic resin having dispersed therein a solution obtained by dissolving an anticoagulant in a solvent. The composition may additionally comprises dispersed therein at least one member of the group consisting of (i) an inorganic substance pulverized to an average particle diameter of not more than 0.1 mm, (ii) a water-absorbing resin powder, and (iii) water-absorbing resin fibers. The resin composition has lasting antithrombic effects and has antithrombic property not merely on the surface of the resin but also throughout the entire resin interior.
