Alifatski segmentirani poliuretani su dobijeni jednostepenim postupkom u katalizovanoj reakciji polikarbonatnog diola heksametilen-diizocijanata i 1,4-butandiola. Variranjem odnosa polaznih komponenti, menjan je udeo tvrdih segmenata (TS, 17, 24, 30 i 42 mas.%).

Aliphatic segmented polyurethanes were prepared by one-step procedure in catalytic reaction between polycarbonate diol, hexamethylene-diisocyanate and 1,4-butandiol (as chain extender). The hard segment content TS was varied (17, 24, 30 and 42 wt. %) by changing the ratio of starting compounds.
