| Abstract | Summar The melting behavior and crystallization kinetics of PBNT copolyesters were studied using differential scanning calorimetry (d.s.c.) The Avrami exponent, n, increased from 2.5 to 3.0 with increasing of annealing temperature between 161 '0 and 170 °C . The Avrami rate constant K increased with naphthalene content while activation energy decreased with naphthalene content. PBNT copolyesters showed three melting peaks, namely minor, lower and upper peaks respectively. The minor peak and lower peak grew with the increasing annealing temperature and holding time, while upper peak decreased. When scanning rate increased, minor peak and lower peak shifted to high temperature but upper peak decreased. |
