Non-polar hydrophobic poly(isobutylene)glycol (PIBG) was substituted for poly(tetramethylene ether)glycol (PTMEG) in poly(ether urethanes) based on 4,4'-methylenebis-(phenylisocyanate) (MDI) and 1,4-butanediol (BD) as chain extender. Two series of polyurethanes differing in their soft segment length, polymer composition, and hard segment content were

The adhesion of platelets to a series of segmented polyurethanes having sulfonate groups in the hard segment is reported. The polyurethanes were synthesized using sulfonated chain extenders of different structure. Analogous control materials without sulfonate groups also were studied. Adhesion

A multiblock copolymer composed of poly(ethylene oxide) (PEO) and poly(tetramethylene oxide) (PTMO) and which forms a physical hydrogel was blended with Pellethane, a commercial segmented polyurethane (SPU) developed for various biomedical devices, to provide a PEO-rich surface with improved stability.
