Research Abstract |
In order to investigate the phase separarion phenomena of polymer alloys such as PC/PMMA,PS/SBR and PET/PP,we have constructed an apparatus for measuring the phase separation temperature and the p-v-T properties of polymer alloys.In this report, the phase diagrams, thermal properties, morphology and p-v-T behavior for various polymer alloys are discussed. We concluded from the above discussion that the lower critical solution temperature (LCST) was observed at PC/PMMA polymer alloys.The DSC curve for polymer alloys appeared two peaks by heat absoption or dispation in the its curve, those peaks show glass transition temperature (T_g) , melting point (T_m) and specific heat (C_p) of base polymer comprising the polymer alloys, respectively.In PC/PPMA polymer alloys, the morphology of PC component (*50wt%) before phase separation was observed dispersing with the fine PC particles, whereas it after phase separtion was observed agglomerating with the large-sized PC particles.The v-T curves of PET/PP polymer alloys in each content ratio are between PET and PP itself at atmospheric pressure.And the compressibility increased under solid state, decreased under liquid state with increasing PET content.
