Abstract

Accordingly, the invention provides a process to prepare a polyester resin having an acetaldehyde concentration of no more than about 1 ppm, which process comprises the steps of: a) reacting ethylene glycol with terephthalic acid or an ester thereof, and isophthalic acid or an ester thereof under constrained reaction conditions effective to prepare a melt phase polymer having an IV in the range of 0.38 dl/g to 0.52 dl/g and a diethylene glycol content of no more than 5 mole% (based on the diol content of the resin); b) recovering the melt phase polymer from step a) as the pre-polymer used in step c); and c) subjecting at least a portion of the pre-polymer recovered in step b) to elevated temperatures over a period of time to elevate the IV to a range of 0.60 dl/g to 0.90 dl/g. The resultant resin can be transformed into a bottle preform, which, when blown, forms a bottle suitable for packaging of mineral water.
