The microkinetics of crystallization and the melting behavior of solid-state polymerized poly(ethylene terephthalate) (PET) have been studied. After correlating crystallization data with secondary nucleation theory and a single regime of growth, a positive correlation was found between molecular wei

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
## Abstract A simple kinetic model capable of describing the behaviors of solidβstate polymerization (SSP) of poly(ethylene terephthalate) (PET) has been developed. According to this model, there are two types of end groups, namely active end groups and inactive end groups, and the solidβstate poly
The main variables involved in solid-state polymerization of PET homopolymers, originally with molecular weight within the commercial range, were sequentially studied to determine their influence in polymerized products. These variables were precursor crystallinity, catalyst, and time and reaction t
