초록
PET 중축합반응에서 Sb2 O3 촉매의 효율을
The polycondensation reaction of PET was required that Sb2O3 catalysts can act effectively through physical transform, in order to obtain this effectiveness, Sb2O3 powder is transformed into liquid solution as dissolving in EG, and than liquid-phase catalysts are made by this liquid solution as mixing with glycols having different solubility. The reaction of PET polymerization efficiency is predicted by using liquid-phase catalysts. In this results, PET were synthesized using catalysts 4 wt% Sb2O3 glycol catalysts and triphenyl phosphate (TPP) as thermal stabilizer in BHET oligomer, and reaction rate and properties of polymerized PET were investigated under different amount of thermal stabilizer. The PET sample using thermal stabilizer 10 ppm and EG-BHPP (Sb2O3 4%) liquid-phase catalyst had high degree of fast polycondensation and inherent viscosity (I.V.) of 0.931 dL/g and the propagation rate (p) was fast polymerization. It was founded that degree of polycondensation increased rapidly in spite of increased of thermal stabilizer. The PET having I.V. of 0.65 dL/g was obtained by using liquid-phase catalyst, for 1-2 hours reaction time.
