Abstract:Values of the Flory-Huggins interaction parameters c were predicted on the base of mixing enthalpy H M for nitrocellulose-s-diethyldiphenylurea system. The phase diagram of the system and the glass transition temperature of mixtures T g12 were estimated using calculated c parameters. The predicted glass transition temperatures were in accordance with values determined experimentally. This revised version was published online in July 2006 with corrections to the Cover Date.
Keywords:phase diagram  cellulose nitrate  s-diethyldiphenylurea  DSC  interaction parameter  glass transition temperature
