Thermoplastic Polyurethane Elastomers : Synthesis, and Study of Effective Structural Parameters (original) (raw)

In this study two classes of polyols, a polyether and a polyester, are used for synthesizing thermoplastic polyurethane elastomers . These elastomers are prepared by chain extension of polyol/toluene diisocyanate by prepoly- mer method and a variety of chain extenders, The effect of polyester and polyether polyols and chain extenders on thermal stability have been invest- igated by studying their morphology using dynamic mechanical thermal analysis (DMTA), and thermogravimetrlc analysis (FGA). The physical and mechanical properties of prepared polyurethane elastomers are measured. The obtained results are investigated and discussed.
