Segmented polyurethanes containing soft segments with lower molecular weight exhibit shape-memorizing properties. Structure and properties of shape-memorizing polyurethanes (S-PUS) were studied. S-PUS are characterized by a rather high glass transition temperature: Tg of S-PUS is usually in the rang
## Abstract Modification of existing polymers leads to enhancement of many desirable properties. So, a hyperbranched polyurethane (HBPU) of monoglyceride of __Mesua ferrea__ L. seed oil, poly(ฮตโcaprolactone)diol (__M__~__n__~ = 3000 g mol^โ1^), 2,4โtoluene diisocyanate, and glycerol with 30% hard s
