Summary

Three methods of synthesis of polyurethanelmldes (PUI) from pyromellitlc dlanhydride, 4,4'-dllsocyanate of dlphenyl-methane and polyester- or polyetherdiols (in solution, in bulk and in concentrated solution) have been presented. The thermal properties of PUI have been compared with those of the previously prepared thermoplastic polyurethanes (PUT) by the methods of derivatography (DTA and TGM) and thermomechanical analysis and a much higher thermal stability of PUI has been found.
