Abstract
Stress cracking in poly(alkylene terephthalate) articles of manufacture is prevented by applying to the article a hydrophilic-substituted aromatic hydrocarbon having either an alkyl or aryl side chain, such as, sodium xylene sulfonate. Preferably, the stress crack inhibitor is applied to the article in the form of an aqueous fatty acid-based lubricant.
