| Özet |
| Poly(bismethoxyphosphazene) (PBMP) was synthesized, giving polymer melts with Tg = −70.9 °C. The chain dynamics of melts and DMF solutions of poly(bismethoxyphosphazene) (PBMP) was investigated by Small-Angle Neutron Scattering (SANS). The radius of gyration Rg was found as 144.7 ± 0.2 Å, and the average MW from SANS was 95000 Da. DMF revealed to be a good solvent for this polymer. From the scattering intensity of polymer solutions for high q-data, the slope was −1.647 in almost exact agreement with the expected excluded volume exponent by Flory which is 5/3 affirming the good solvent property of DMF. GPC measurements of THF solutions were evaluated based on a universal calibration of polystyrene standards resulting in a rather similar value of 1.05 × 105 Da. Another series of SANS experiments was done with solutions of LiSO3CF3 (LiTf) in the title polymer. They also showed low Tg … |
