Implication

Methodological study reveals improved precision of specified area under band analysis in polyolefins, suggesting superior tracking of plastic degradation during accelerated aging.

Key Points

To evaluate existing literature methods for determining the carbonyl index of polyolefins and introduce a more accurate specified area under band methodology using ATR-FTIR spectroscopy.
Assessed and compared established literature techniques for calculating the carbonyl index in polyethylene and polypropylene samples.
Developed the specified area under band (SAUB) protocol using attenuated total reflectance Fourier-transform infrared (ATR-FTIR) spectroscopy under accelerated aging conditions.
Conventional literature methods were found to be inconsistent, inaccurate, and unable to resolve meaningful changes in carbonyl peak evolution over the course of accelerated aging.
The SAUB methodology demonstrated higher analytical precision and successfully distinguished the differing extents and degradation rates between polyethylene and polypropylene exposed to identical aging regimes.
