Abstract

Understanding the effects of blood on poly(urethanes) requires a knowledge of the interactions between the polymer and individual blood components. This study examines the calcium-poly(urethane) interaction. Calcification has been associated with a loss of mechanical properties leading to premature failure of polymer implants. Using tensile testing, dynamic mechanical testing, differential scanning calorimetry and infrared spectroscopy, this study observed the changes in structure and properties of a poly(ether urethane) when calcium is blended with it. It is shown that the polyether soft segment may serve as an initiation site for calcification, leading to premature failure.
