| Four kinds of poly(amide-block-ester)s (PAE) with the same hard blocks of PBT and different soft blocks of selected diamines and dimerized fatty acid were synthesized; results of their investigations are presented. The following experimental techniques were used: differential scanning calorymetry (DSC), dynamic mechanical thermoanalysis (DMTA), and dielectric spectroscopy (DETA). Based on the obtained results, an influence of the particular diamines onto phase structure and physical properties of the investigated PAE is discussed. |
