Abstract: The present invention relates to a specific polyethylene terephthalate (PET) allowing to produce a stretch blow molded PET bottle having superior resistance to environmental stress cracking when the inner or outer surface of the bottle is treated with stress cracking causing chemical substances and to a method of manufacturing such specific PET. The invention also relates to a stretch blow molded bottle made of such PET and a preform of such a bottle. The invention further relates to the use of the specific PET for the manufacture of a stretch blow molded PET bottle having said superior resistance to environmental stress cracking or the manufacture of a preform of such a PET bottle.
