Principles of Solid-Phase Polycondensation of Poly (ethylene terephalate) |
| |
| Abstract: | Three kinds of methods for preparing high molecular weight of poly(ethylene terephalate)(PET) were briefly introduced. The basic principle of solid-phase polycondensation of PET and all reaction formula and effects on solid-phase polycondensation of PET were emphatically described, such as materials route of prepolymer, equilibrium between carboxy end group and hydroxy end group, chip shape and size, catalyst, by-products, crystal morphology and crystallinity, diethylene glycol content and melting point, molecular weight distribution, comonomer etc. At last, dynamics of solid-phase polycondensation of PET were explained, such as effects of temperature and reaction time on solid-phase polycondensation rate, dynamics of cold sold-phase polycondensation etc. 17 references were presented. |
