Abstract
Rheological behavior of NEP type ultra bright polyester and common ultra bright PET was investigated by means of a capillary rheometer. It showed that both NEP type polyester and common ultra bright PET melt were pseudoplastic. The viscous activation energy of NEP type polyester was lower than that of common ultra bright PET. The effect of temperature on the melt viscosity of ultra bright PET was more sensitive than that of NEP type polyester. NEP type polyesters was more similar to Newton fluids than common ultra bright PET at low shear rates. The non-Newtonian index at high shear rates of NEP type polyester was greater than common ultra bright PET. The non-Newtonian index at high shear rates of ultra bright PET enhanced more than that of NEP type polyester with the increase of temperature.关键词
