Oxidative degradation of polylactide (PLA) and its effects on physical and mechanical properties [PDF]

open access: yes, 2014
The thermo-oxidative degradation of polylactide (PLA) films was studied between 70 and 150 C. It was shown that the oxidative degradation of PLA leads to a random chain cission responsible for a reduction of the molar mass.
