Autor: Shoutarou Suzuki, Hisayuki Nakatani, Kenichi Kawamura, Boping Liu, Masanao Ishikawa, Minoru Terano, Norio Manabe

Publikováno v: Polymer Testing. 24:994-997

In this study, a novel potentiometric titration of hydroperoxide in degraded polypropylene (PP) is proposed. This titration is quite sensitive compared with the conventional ones such as UV and manual titrations, and its detection limit was about 2 m
