- Аннотация: A melting temperature of 90.4°C (complete amorphization) for macromolecular poly-3,3-bis(azidomethyl)oxetane is determined via the hydrostatic-weighing method. This value corresponds to the end of the endothermic peak of the DSC thermogram and is ~10°C higher than the maximum value. The amorphization of the polymer is found to proceed mainly owing to thermomechanical destruction of the crystallites, and only a very small part of them is melted purely thermally at the temperature of complete amorphization. The melting temperature is significantly reduced in the presence of the oligomer fraction in the polymer. The density and equilibrium heat of fusion of the crystalline regions, which coincide for various polymer samples, are found with consideration for the data of X-ray scattering.
