Abstract:

In order to study the composition and content of oligomers extracted from high molecular weight poly(ethylene terephthalate) (HMW-PET) and its invluence on the properties of HMW-PET, the extraction and precipitation of oligomers were performed on fiber-grade PET, solid-state polycondensation (SSP) and liquid-state polycondensation (LSP). The obtained oligomers were characterized by advanced polymer chromatography and differential scanning calorimetry. The results show that the precipitation process could separate oligomers quickly and completely. The extraction process can obtain oligomers with a good accuracy and less than 3%. The difference of oligomers content and  component is significant between SSP product and LSP products. The oligomers extracted show endothermic peaks at about 246.6 and 310.7 °C, respectively, and cyclic trimer accounts for the highest proportion in oligomers for all products. The cold crystallization temperature of fiber-grade PET and HMW-PET treated by extraction is increased. The melt enthalpy of fiber grade PET decreases by the extraction, while the enthalpy of HMW-PET become higher.
