摘要：

Attempts were made to minimize the amounts of acetaldehyde (AA) and formaldehyde (FA) generated during the processing of PET bottle preforms. Various radical scavengers and chain end capping compounds were added to heated PET samples. and p-aminobenzoic, 3,5-dihydroxybenzoic and 4-hydroxybenzoic acids appeared to be the most efficient stabilizers under static laboratory conditions. They were less active under actual processing. Nevertheless the same trends were observed.
