Long‐Time Thermal Aging of Perfluoroalkoxy Polymers for Electrical Insulation: Structural and Physical Properties Evolutions

Journal of Applied Polymer Science, Volume 143, Issue 39, October 15, 2026.
This work focuses on the investigation of the influence of a long‐time exposition to accelerated thermal aging on the physicochemical structure and properties of PFA. Results show a decrease in the melting temperature and crystal ratio due to chemical aging.

Classification Accuracy of Equated Item Response Theory (IRT) Scores and Sum Scores

, 2020
The item response theory (IRT) framework is commonly used for scoring and equating in high stakes tests to classify individuals into performance categories. However, IRT model misspecification such as assuming unidimensional IRT model for multidimensional items can mitigate any advantages gained making sum score-based equating techniques more desirable.
