Novel Polybutadiene Diols for Thermoplastic Polyurethanes
Krasol® polybutadiene diols are anionically polymerized products characterized by very narrow molecular weight distribution, linear structure of polymer chains and the absence of species with functionality higher than 0.2. These unique features make them suitable as hydrophobic polyol components for use in thermoplastic polyurethanes (TPUs). Various TPU formulations were developed using polybut...
متن کاملvalsalva maneuver and strain-related ecg changes
background during the four steps of the valsalva maneuver (vm), opposite changes can be observed in some physiologic parameters. manifestations of the vm in the electrocardiogram (ecg) have been studied in detail, but there have been few reports comparing vm-related biochemical and hemodynamic changes with a focus on the strain phase of the vm. objectives we studied strain-related ecg changes d...
متن کاملStress-Strain Behavior of Thermoplastic Polyurethane
The large strain nonlinear stress-strain behavior of thermoplastic polyurethanes (TPUs) exhibits strong hysteresis, rate dependence and softening. Thermoplastic polyurethanes are copolymers composed of hard and soft segments. The hard and soft segments phase separate to form a microstructure of hard and soft domains typically on a length scale of a few tens of nanometers. Studies have revealed ...

متن کاملBiodegradable thermoplastic polyurethanes incorporating polyhedral oligosilsesquioxane.
A new hybrid thermoplastic polyurethane (TPU) system that incorporates an organic, biodegradable poly(D, L-lactide) soft block with a hard block bearing the inorganic polyhedral oligosilsesquioxane (POSS) moiety is introduced and studied. Changes in the polyol composition made through variation of the hydrophilic initiator molecular weight show direct control of the final transition temperature...
