Abstract:
A thermoplastic polyurethane having prolonged biostability has tertiary amino groups in the polymer chain. Protonation of the amino groups with an aqueous acid causes the polymer to absorb up to 1,700% by weight of water and swell. The protonated amino groups form a complex with an antithrombogenic agent to give an antithrombogenic polyurethane. The invention includes a shaped article of the polyurethane.
