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 Segmented polyurethane (PU) films from castor‐oil‐based PU prepolymer with different hard‐segment compositions and nitrolignin (NL) were synthesized. Diisocyanates (DIs), such as 2,4‐tolylene DI (TDI) and 4,4′‐diphenylmethane DI (MDI), 1,4‐butanediol (BDO) as a chain extender, and trime
