Process for producing polyethylene terephthalate using a specific catalyst stabilizer system |
摘要 |
A novel process to produce polyethylene terephthalate (PET) using a specific catalyst stabilizer system is described. The catalyst stabilizer system is specific for producing PET wherein the polycondensation catalyst is a titanium and the stabilizer possesses an irreversible oxidation potential of at least +2.0 volts versus SCE. The novel process results in PET having acceptable color and low acetaldehyde content.
