A thermodynamic model for the equilibrial process zone ahead of a crack in polycarbonate is developed from the recently proposed Chudnovsky model and experimental characterization of the process zone. Based on the model, the force for evolution of the process zone is proposed from the consideration

## Abstract The experimental and modeling studies are presented on the melt polycondensation of poly(ethylene terephthalate) by a gas sweeping process. In this process, low molecular weight prepolymer is polymerized to a higher molecular weight polymer in a molten state at ambient pressure as ethyl
