Abstract In this survey of the industry, it is shown that despite the partial dissatisfaction with antimony-based polycondensation catalysts these catalysts are expected to remain the mainstay of industrial PET polycondensation catalysis. This is despite the intensive efforts invested in the search of other, stable and inexpensive non-antimony catalysts, such as those based on titanium, aluminium, and several traodtion metals such as molybdenum, cobalt and zirconium.
