Quantifying the cooperative evolution of microphase segregation and nanostructural order in annealed polyurethanes of <span>MDI‐BDO‐PTHF</span> Open
Here, we quantify the relationship between microphase segregation and local structure development in thermoplastic polyurethanes. Samples were prepared with varying ratios of 4,4′‐methylene diphenyl diisocyanate (MDI) and 1,4‐butanediol (B…

Block length distribution, morphology, and property of thermoplastic polyurethanes affected by production method: A polymer‐by‐process investigation Open
Two thermoplastic polyurethanes (TPUs) based on the same monomers and composition were produced by two different production methods – hand mix batch process and continuous band casting. The soft segment was poly(hydrofuran) (PTHF) with a m…

Melting and solidification of thermoplastic polyurethanes as a function of nucleating agents Open
The solidification of two thermoplastic polyurethanes (TPU) appears as a two‐stage segregation (large‐scale allocation of hard‐phase entities, short‐scale granulation in the allocated entities). Following consolidation may raise the hard‐p…

Melting, Solidification, and Crystallization of a Thermoplastic Polyurethane as a Function of Hard Segment Content Open
Thermoplastic polyurethanes (TPU) with varying hard segment contents (HSC) are monitored during melting and solidifying (, T max = 220 ° C) by small‐angle and wide‐angle X‐ray scattering (WAXS and SAXS). Hard segments: MDI/BD. Soft segment…
