Abstract
Thermophysical properties of polyurethane ureas by thermogravimetry and differential scanning calorimetry were studied. It was shown, that investigated polyurethane ureas are heat-resistant up to 523 K. The structure of polyurethane ureas, containing folate derivative of ferrocene, by wide-angle and small angle X-ray method for different content of folate-derivative of ferrocene was investigated. Wide-angle X-ray diffraction data revealed that the introduction of 0.01 mole of folate derivative of ferrocene to the PUU structure leads to the change of period alternating arrangement of flexible and rigid blocks of PUU, significant degradation of heterogeneous structure, but does not cause changes in amorphous structure of the polymer.
