The kinetics of polycondensation and copolycondensation reactions of bis(3hydroxypropyl) terephthalate (BHPT) and bis(2-hydroxyethyl) terephthalate (BHET) as monomers were investigated at 270ยฐC, in the presence of titanium tetrabutoxide (TBT) as a catalyst. BHPT was prepared by ester interchange rea

Poly(ethy1ene terephthalate) (PET) was synthesized from its monomer bis-hydroxyethyl terephthalate (BHET), in the presence of Sb,O, catalyst. A second order irreversible reaction model was developed, and the apparent rate constant was evaluated by observing the course of intrinsic viscosity change.
This research discussed the effect of the addition of antimony catalyst on diethylene glycol (DEG) formation in poly(ethylene terephthalate) (PET) synthesis. It was found that antimony catalyst increased DEG formation in the preparation of PET, in particular, during the esterification stage and also
