| The synthesis of PET begins with the esterification of terephthalic acid or dimethyl terephthalate with ethylene glycol to produce bis(hydroxyethyl)terephthalate (BHET). BHET is then polymerized to approximately 30 repeating units (Awaja and Pavel, 2005). Next, to reach a degree of polymerization (DP) of about 100 repeating units, condensation is carried out at temperatures >270°C and pressures >50 Pa (Ravindranath and Mashelkar 1986). To produce bottle-grade PET, DP must be >150 repeating units, which is usually accomplished by solid-state polymerization, a process that requires temperatures >200°C, pressures >100 Pa, and incubation times of at least 15 hours (Al-Ghatta et al. 1997). |
