Development of Phosphorous-containing Copolymerizing Flame Retarding PET Products;

The distillation column (also called process column) for separating ethylene glycol/water in polyethylene terephthalate (PET) process was accurately simulated and calculated by process simulation technology.

Based on study of solid phase polycondensation kinetics of polyethylene terephthalate (PET), a mul-ti - component model was established in order to simulate the molecular weight distribution of PET in the process of solid phase polycondensation.

Highly transparent and conducting polythiophene polyvinyl alcohol polyethylene terephthalate (PTh PVA PET)composite films are obtained by depressed distilling chemcal vapor deposition.

Application of Rietveld Method in the Structure Analysis for Semi-crystalline Poly(ethylene terephthalate);

The model that describes the online molecular mass distribution(MWD) for the polycondensation reaction process is developed by the method of generation function,in which a reaction process of poly(ethylene terephthalate)is taken as an example.

Some methods for synthesis of ethylene glycol via non oil routes, which have been extensively studied in the world, are presented involving synthesis of ethylene glycol from syngas, the method with formaldehyde as its starting material, methanol based methods, poly(ethylene terephthalate)decomposition, etc.
