| Abstract: | A series of polyester-based thermoplastic polyurethanes(TPU) elastomer were prepared from polyester polyol,diphenylmethane-4,4'-diisocyanate(MDI) and 1,4-butanedio(BDO) by one-step process.The effects of the type of soft segment,mass fraction of hard segment and relative molecular mass of soft segment on the mechanic properties,dynamic viscoelasticity and damping properties of TPU were studied.The atomic force microscope(AFM) analysis was applied to investigate the soft/hard segment micro-phase separation in TPU. |
