The effect of a small amount of poly(ethylene naphthalate) (PEN) in its blends with poly(trimethylene terephthalate) (PTT) on isothermal melt-crystallization kinetics and spherulitic morphology of the blends was thoroughly investigated. The maximum PEN content in the blends was 9wt%. Due to the single composition-dependent glass transition temperature (T g ) that was observed for each blend,...
Non-isothermal melt-crystallization kinetics and subsequent melting behavior of poly(trimethylene terephthalate) (PTT) have been investigated by differential scanning calorimetry (DSC). The Avrami, Tobin and Ozawa equations were applied to describe the kinetics of the crystallization process. Both of the Avrami and Tobin crystallization rate parameters (i.e. K A and K T , respectively)...
