Besides methyl methacrylate (MMA), what other types of compounds are revealed in the pyrolyzates of poly(methyl methacrylate) (PMMA)?

Label:chem

Topic
While MMA is the primary product of PMMA pyrolysis, the thermal degradation process can also generate secondary products due to reactions in the hot vapor phase. Identifying these additional compounds provides insights into the complex mechanisms of polymer decomposition.
Answer
Non-targeted analysis of PMMA pyrolyzates has revealed the presence of a variety of compounds beyond the predominant methyl methacrylate (MMA), with significant contributions from ester and carboxylic acid groups. These secondary products are formed from reactive species generated during the breaking of polymeric chain bonds.
