Summary
This study examines how the carbon mass fraction in remnants of polypropylene granules and in microplastics changes as a function of the carbonyl index following aging. The data provide a quantitative basis for tracking polymer degradation and carbon transformation during environmental weathering of plastic materials.
The carbon fractions presented are normalized using the stoichiometric proportion of carbon in PP.
