A new comprehensive model for solid-state polycondensation (SSP) of polyethylene tercphthalate (PET) has been developed, which interprets a number of hitherto unexplained observations. Degradation and other side reactions which were neglected in the earlier models for SSP process of PET are included

A mathematical model for solid-state polymerization of poly(ethylene terephthalate) was developed. The effects of temperature and chain entanglement on chain mobility were considered to estimate the rate constants of chemical reactions. The diffusivities of volatile byproducts could be determined us
A general kinetic scheme for the polycondensation step of the PET formation has been used to establish the mole balance equations of various functional groups in batch reactors. An objective function has been defined which aims to attain a desired degree of polymerization in the shortest time, has a
