What is methyl methacrylate (MMA) and how is it generated from poly(methyl methacrylate) (PMMA) pyrolysis?

Label:chem

Topic
Methyl methacrylate (MMA) is the predominant monomer produced when poly(methyl methacrylate) (PMMA) undergoes thermal decomposition. The process involves the thermal degradation of PMMA, primarily through chain scission, which yields MMA. This is a crucial aspect for understanding polymer recycling and fire safety.
Answer
Methyl methacrylate (MMA) is the main monomer product of poly(methyl methacrylate) (PMMA) pyrolysis, which is the thermal decomposition of PMMA under heat. Studies have consistently shown that PMMA predominantly decomposes into MMA, with reported yields typically ranging from 80% to 100%. This understanding is vital for optimizing PMMA recycling processes and developing accurate fire safety models.
