| abstract |
The invention presents an antithrombotic resin which is prepared by blending at least one type of antithrombotics, in polyurethane or polyurethane urea polymerized by using at least one type of polyether diol selected from the group consisting of polyol containing a polyoxyethylene group expressed in formula (I) n n .paren open-st.CH.sub.2 CH.sub.2 O.paren close-st..sub.n (I) n n (where n is a number-average degree of polymerization of 1 to 100) and polyol containing a polyoxyethylene group expressed in formula (II) n n .paren open-st.CH.sub.2 CH.sub.2 CH.sub.2 CH.sub.2 O.paren n n close-st. m (II) n (where m is a number-average degree of polymerization of 1 to 100). This antithrombotic resin is capable of eluting the antithrombotic in the blood for a long time at high concentration. By using the antithrombotic resin of the invention, antithrombotic tube, antithrombotic film, antithrombotic coat, and others are obtained. |
