Various segmented polyurethane materials with a polyurethane hard segment (HS) content of 40 wt % were prepared by bulk polymerization of a poly(tetramethylene ether) glycol with M n of 2000, 1,4-butanediol, and various diisocyanates. The diisocyanates used were pure 4,4Ј-diphenylmethane diisocyanat
Many polyurethane elastomers display excellent mechanical properties and adequate biocompatibility. However, many medicalgrade polyurethanes are prepared from aromatic diisocyanates and can degrade in vivo to carcinogenic aromatic diamines, although the question of whether the concentrations of thes
