Almtract--Segmented polyurethanes based on polypropylene glycol, butane diol and a mixture of (diphenylmethane diisocyanate)/(toluene diisocyanate) (MDI/TDI) were prepared and characterized. Soft segment concentration was kept constant at 50% in all polymers but the structure of the hard segment was
## Abstract The phase‐separation behavior and morphology of polycarbonate‐based polyurethanes were investigated as a function of the soft‐segment molecular weight and chemical structure and the 4,4′‐diphenylmethane diisocyanate/1,4‐butanediol based hard‐segment contents. Polarized optical microscop
