摘要：<p>Melt processable polyurethaneureas are prepared from a diisocyanate, a polyglycol, a diol chain extender and an amine terminated polyether. Water may be included as a reactant, and the polymer may contain an additive such as a radiopaque material and a coating of an antithrombogenic agent or an antimicrobial agent. The invention includes a one-pot bulk polymerization method for preparation of the polymers.</p>
