The effect of branching on the crystallization behavior of poly(ethylene terephthalate) has been examined by nonisothermal crystallization studies, using DSC. It was found that branching causes a significant change in the crystallization behavior, in that the Avrami exponent n lies between 1 and 2,

A series of N-alkyl-p-toluenesulfonamides (ATSA) were synthesized and identified. The measurement of solution viscosity of poly(ethy1ene terephthalate) (PET) proved that ATSA does not react with PET during the melting process of PET/ATSA mixtures, and consequently does not cause any decrease of mole

The experiments were carried out in excess ethylene glycol (EG) and poly(ethylene terephthalate) (PET) oligomer in the presence of zinc acetate as catalyst at 190Β°C. It was found that during the glycolysis reaction, the monomer and dimer were contained in the liquid phase. After 2 h of the glycolysi
