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 Synthesized shape‐memory polyurethane (PU) block copolymers were used to prepare electrospun nonwovens via electrospinning. PU solutions were prepared with a mixed solvent of __N,N__‐dimethylformamide and tetrahydrofuran. The electrospun PU nonwovens were prepared with hard‐segment conc
