摘要

The oxidative stability of poly(butylene terephthalate) was investigated over the range l75 to 220 deg C by isothermal differential calorimetry. It is shown that this property is affected by a fast recrystallization process, which takes place between 200 and 220 deg C, with a maximum around 208 deg C. In fact, recrystallization produces an increase of the crystallinity degree of the polymer, which enhances its resistance to oxidation, as proven by the longer oxidation times detected.
