Abstract
Stabilization of poly(ethylene terephthalate) (PET) against hydrolysis can be performed by lowering the carboxylic end group concentration. Therefore a polycarbodiimide and a bisepoxy compound have been used. For a proper stabilization an excess of polycarbodiimide should be added, so that newly formed carboxylic end groups are also removed. The bisepoxide used shows a relatively low reactivity towards carboxylic end groups. Sodium benzoate and triphenyl phosphine catalyze the reaction, albeit that the first, being relatively basic, strongly induces cross-linking reactions, in contrast to the last catalyst.
