Antimony Antimony trioxide is the major catalyst used to polymerise PET. In principle, the catalyst will remain in the PET after polymerisation. Typically, concentrations of antimony in PET bottles are below of 300 mg per kg PET (Welle and Franz 2011). Alternative catalysts for the polymerisation of PET have also been process consisting of transesterification-polycondensation and optionally, a solid-state polymerisation process. The workhorse catalyst for the transesterification and polycondensation process is antimony trioxide, used at a concentration level of 250 - 300 ppm. Over 95% of worlds production of PET use antimony trioxide as the catalyst.
