Abstract Poly(ethylene terephthalate) (PET) was synthesized from its monomer bis‐hydroxyethyl terephthalate (BHET), in the presence of Sb 2 O 3 catalyst. A second order irreversible reaction model was developed, and the apparent rate constant was evaluated by observing the course of intrinsic viscosity change. At 278°C, the apparent rate constant in the presence of 0.025% (by weight) of Sb 2 O 3 was found to be 0.945 L/mol h.
