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 Poly(ε‐caprolactone)‐based segmented polyurethanes (PCLUs) were prepared from poly(ε‐caprolactone) diol, diisocyanates (DI), and 1,4‐butanediol. The DIs used were 4,4′‐diphenylmethane diisocyanate (MDI), 2,4‐toluenediisocyanate (TDI), isophorone diisocyanate (IPDI), and hexamethylene di
