Abstract
The melting and mixing enthalpy of the binary system nitrocellulose and N-nitrodiethanolamine dinitrate (DINA) was determined by DSC. The mixing enthalpy H Mmax = 1.95 kJ mol−1 had maximum at mass fraction x wDINA=0.46. The influence of samples storing on glass and endothermic transitions were studied. The temperature range of glass transition broadened with x wDINA what proved the increase of samples heterogeneity. For x wDINA≤0.750 no influence of samples storing on the phase changes was observed. The heat capacity change decreased and temperature range of glass transition increased for x wDINA≤0.500 what indicated the reduction of glass phase fraction in studied samples.
