Abstract
The invention relates to methods of making polyurethane derivatives which can be readily further derivatized using stabilizing agents such as anti-calcification agents, anti-thrombogenesis agents, and chemical and mechanical degradation-inhibiting agents. The invention also includes methods of making polyurethane derivatives so further derivatized and to polyurethanes derivatives made using such methods.
