Elasticity and inelasticity of thermoplastic polyurethane elastomers: Sensitivity to chemical and physical structure

Abstract:

Cyclic tensile responses of fourteen polyurethane elastomers were studied, with respect to their chemical composition and physical structure. Hard segment, soft segment and chain extender were varied, while keeping the hard segment fraction at ca 40% and soft segment molar mass at 2000 g/mol. Hard segments were generated from 4,4'-methylene bis(phenyl di-isocyanate) (MDI), or 4,4'-dibenzyl di-isocyanate (DBDI). Physical structure was characterized by X-ray scattering (SAXS and WAXS), revealin...
