| Description | A three series of terpolymers composed of the blocks PTMO $(M_{PTMO}$ = 1000 g/mol) or DLAol $(M_{DLAol}$ = 540 g/mol), PA12 $(M_{PA12}$ = 2000 g/mol) and xGT $(DP_{xGT}$ = 2) with various chemical compositions of ester block were obtained. The series differ in the chemical structure of the flexible block and weight content of the soft phase. The effect of the number of carbons dividing the terephthalate groups on the synthesis, structure and properties of these elastomers has been investigated. To confirm assumed chemical structure Carbon-13 $(^{13}$C NMR) and Proton $(^{1}$H NMR) Nuclear Magnetic Resonance and Fourier-transform Infrared Spectroscopy (FT-IR) were used. The influence of chemical compositions of ester block on the thermal properties and the phase separation of obtained systems were defined by Differential Scanning Calorimetry (DSC), Dynamic Mechanical Thermal Analysis (DMTA) and Wide Angle X-ray Scattering (WAXS). The mechanical and elastic properties were evaluated. |
