Beschreibung
Zusammenfassung:	PURPOSE:To obtain the subject elastomer useful as a medical tool material such as artificial blood vessel, having excellent mechanical strength, flexibility, elasticity and durability by bonding an antithrombogenic compound to a specific polyurethane. CONSTITUTION:(ii) An antithrombogenic compound such as heparin is linked to (i) a polyurethane comprising an A-B-A type block copolymer of a polyoxyethylene (A) and a polyoxytetramethylene (B) as a polyether diol component to give the objective elastomer. A medical tool is obtained from this the elastomer.
