Abstract
Macromolecular material suitable for making anti-thrombogenic artificial organs comprises block polymers contg. blocks of polyamidoamines and blocks of classical polycondensation or polyaddition polymers and may be heparinised to give it antithrombogenic properties. Fabrication of antithrombogenic proteses and artificial organs. Polymer has excellent thermoformability by extrusion, moulding and similar processes to give products with excellent mechanical properties and is also capable of directly and permanently fixing heparin to its surfaces to give thrombo-resistant activity.
