What is PLA UV Degradation Effects on Properties about?

This document summarizes a study on the oxidative degradation of polylactide (PLA) films between 70-150°C. The key findings are: 1) Oxidative degradation leads to random chain scission in PLA, reducing its molar mass. 2) Reductions in molar mass affect the glass transition temperature (Tg) and degree of crystallinity. Tg decreases according to the Fox-Flory theory, while crystallinity increases due to a process called chemocrystallization. 3) A correlation was found between molar mass and strain at br
