  • Polyester resins with a special co-catalyst for high melt poly and SSP reactivity with enhanced color values
    Patent number: 7622545
    Abstract: The present invention relates to a PET resin and a process for producing polyethylene terephthalate (PET) resin having conventional catalysts such as antimony, titanium, tin or germanium compounds and a glycol insoluble tungsten compound or tungsten trioxide or tungsten carbide as co-catalyst. The tungsten compound as a co catalyst increases the rates of solid state polymerization and improves the ‘L’ color value.
