A comprehensive account of the physical / mechanical behaviour of polyurethanes (PU´s) elastomers, films and blends of variable crystallinity. Aspects covered include the elasticity and inelasticity of amorphous to crystalline PUs, in relation to their sensitivity to chemical and physical structure. A study is made of how aspects of the constitutive responses of PUs vary with composition: the polyaddition procedure, the hard segment, soft segment and chain extender (diols and diamines) are varied systematically in a large number of systems of model and novel crosslinked andthermoplastic PUs. Results will be related to: microstructural changes, on the basis of evidence from x-ray scattering (SAXS and WAXS), and also dynamic mechanical analyses (DMA), differential scanning calorimetry (DSC) and IR dichroism. Inelastic effects will be investigated also by including quantitative correlations between the magnitude of the Mullins effect and the fractional energy dissipation by hysteresis under cyclic straining, giving common relations approached by all the materials studied. A major structural feature explored is the relationship between the nature of the hard segment (crystallising | | 出版日期 | Book 2011 | | 关键词 | Crystallization; DBDI; Diisocyanates; Macrodiols; Polyurethanes | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-7091-0514-6 | | isbn_softcover | 978-3-7091-1694-4 | | isbn_ebook | 978-3-7091-0514-6 | | copyright | Springer-Verlag/Wien 2011 |
