Synthesis and In vitro Blood compatibility of Polyurethane Graft Stearyl Poly(ethylene oxide)

Abstract

Abstract: Anew grafted polyether, poly(tetramethylene glycol)-graft-ω-stearyl-poly(ethylene glycol)(PTMG-g-PEG-C₁₈), was synthesized by the cationic polymerization of α-ω-bifunctional PEG macromonomer and THF. Polyurethane-graft-ω-stearyl poly(ethylene glycol)(PEU-g-PEO-C₁₈), the new polyether as a soft segment, was synthesized. The results of platelet adhesion on PEU-g-PEG-C₁₈surface indicated that the polyurethane can resist platelet adhesion on the original surface and pre adsorption albu min surface.

Key words: Polyurethane, Albu min, Blood compatibility
