Process to prepare a polyester resin |
摘要 |
A process is disclosed to prepare a polyester resin having a predetermined acetaldehyde (AA) content whereby the IV of the melt phase resin is constrained to a certain range resulting in a longer SSP time to achieve a higher level of IV for the resin with an AA content of 1 PPM or less. The resultant resin can be transformed into a bottle preform, which, when blown, forms a bottle suitable for packaging of mineral water. |
