چکیده انگلیسی
The y(α) and z(α) plots, which were obtained through transformation of DSC data, are not completely identical at a variety of heating rates. It indicates that the kinetic process dose not follow a single-step curing reaction model and a multi-step process controls it during curing. To approve the non-isothermal analysis result, we carried out further, depolarizing transmittance measurements and optical microscopy observations on the stoichiometric mixture of LCO/D&TGE during curing, at various heating rates. The results of these experiments exhibit that the kinetic process of the investigated system is strongly influenced by altering the mesomorphism features of the sample.
