Abstract
Thermal properties of poly(ethylene 2,6-naphthalate) (PEN)/poly(butylene 2,6-naphthalate) (PBN) blends were investigated by differential scanning calorimetry. Blends containing less than 60 wt% PBN showed double glass transitions, which approach mutually closer with increasing PBN content, whereas a single glass transition was observed for compositions more than 80 wt% PBN. This behavior indicates that the blends with 60 wt% PBN or less separate into two amorphous phases containing both components and the difference in composition between two phases decreases with an increase of PBN content, while a single amorphous phase is formed for compositions more than 80 wt% PBN. This result was supported by melting behavior and crystallization kinetics.
