The research aimed at the selection of polyurethanes synthesized from poly(tetramethylene ether) glycol (PTMEG), as well as from two different isocyanates 4,4′-methylenebis(cyclohexyl)isocyanate (HMDI) and 4.4′-methylenebis(phenyl isocyanate) (MDI) in order to obtain polyurethane with increased resistance to abrasive wear and degradation for bio-medical application. Polyurethanes were fabricated from crystalline prepolymers extended by water. The paper presents preliminary results on polyurethane surface wettability, friction coeffi cient for different couples of the co-working materials such as polyurethane–polyurethane, polyurethane–titanium alloy, polyurethane–alumina, in comparison to commonly used polyethylene–titanium alloy. Shear strength of polyurethane–alumina joint, as well as viscosity of prepolymers were also measured. The values of friction coeffi cient were compared to literature data on commercially available polyurethane with the trade name Pellethane. Polyurethanes obtained are characterized by low abrasive wear and low friction coeffi cient in couple with the titanium alloy, what makes them attractive as possible components of ceramic-polymer endoprosthesis joints.
