Polyurethane ionenes were prepared for the purpose of obtaining polyurethanes with high waterabsorbing power and good elastomeric properties. A series of crosslinked polyurethane ionenes were compared with model polyurethane ionenes, model polyurethanes, and polyurethane ionenes containing increased content of urethane hard segments. The specimens were synthesised by the prepolymer method by using diisocyanate, two types of polyethers, and ionenes at different molar ratios. The surface of specimens were observed by polarizing optical microscopy. Differential scanning calorimetry was examined. The super structure of polyurethane ionenes were discussed in relation to chemical composition and aggregation of chains.
