Examples of PBPAC degradation studies are numerous in the literature, starting with hydrolysis and methanolysis, with complete depolymerization or yields in excess of 80 %, analyzed mainly by infrared spectroscopy and gas chromography. Other studies have focused on the biodegradation of polycarbonates, but this time with highly variable yields. When it comes to aliphatic polycarbonates, they can sometimes exceed 50 %, or even 70 % yield on rare occasions, in the case of PBPAC, degradation barely reaches 30 %, leaving considerable room for improvement in this type of approach. Unlike for chemical methods, degradation products are then analyzed by a wider variety of methods, including mass loss, infrared spectroscopy and size-exclusion chromatography (SEC). Finally, a certain number of studies have focused on weaker degradation processes, such as heat treatment or UV irradiation, using analytical methods such as SEC, MALDI-TOF, yellowness index, FT-IR, or SEM. This very wide range of analytical methods is often used inconsistently between different studies, or even within the same study, creating a lack of clarity in understanding the phenomena involved. In particular, some analysis methods used are actually not suitable for the degradation percentages studied, and can lead to misinterpretation of the actual level of degradation. Generally speaking, this heterogeneity within the available literature makes it particularly difficult, if not impossible, to compare degradation methods, as no standardized experiments have been carried out, further limiting the scope of such studies.
