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,

The isothermal and dynamic crystallization behaviors of polyethylene terephthalate (PET) blended with three types of liquid crystal polymers, i.e., PHB60-PET40, HBA73-HNA27, [(PHB60-PET40) -(HBA73-HNA27) 50 : 50], have been studied using differential scanning calorimetry (DSC). The kinetics were cal
A series of copolyesters were prepared by the incorporation of p-hydroxybenzoic acid (HBA), hydroquinone (HQ), and terephthalic acid (TA) into poly(ethylene terephthalate) (PET). On the basis of viscosity measurements, high molar mass copolyesters were obtained in the syntheses, and 1 H-NMR analyses
