Resum
In this Note we would like to report on the analysis of the microstructure of segmented polyurethanes by 13CNMRmaking use of the signals arising from nonprotonated aromatic carbons which appear to be sensitive to dyads sequence distribution. The polyurethanes here studied were obtained from poly(tetramethylene glycol) (PTMG) as macrodiol soft segment, 1,4-butanediol (BD) chain extender, and 4,40'-methylenediphenyl diisocyanate (MDI) as hard segment.The results obtained in this work provide a rel...
