Abstract

PURPOSE:To obtain an anticoagulant material composed of a polymer easy in MW planning, by using polyurethane or polyurethaneurea having polyalkylene oxide having narrow MW distribution in the side chain thereof. CONSTITUTION:In preparing an anticoagulant material composed of polyurethane or polyurethaneurea having polyalkylene oxide having narrow MW distribution in the side chain thereof, two methods can be adapted. At first, the side chain part is prepared. In order to obtain one having narrow MW distribution, immortal polymerization is adapted. When the side chain is introduced at the time of the production of a prepolymer, polyalkylene oxide is allowed to be present when isocyanate and polyalkylene glycol are reacted in dimethylacetamide. When the side chain is introduced at the time of the chain extending reaction of the prepolymer, a prepolymer into which no side chain is introduced is prepared. The introduction of the side chain can be performed by reacting polyalkylene oxide having diol at one terminal thereof using diamine or diol.
