Detailed Kinetic Analysis of Slow and Fast Pyrolysis of Poly(methyl methacrylate)-Flame Retardant Mixtures

•Kinetics of PMMA decomposition is slowed down by the addition of 5 wt.% Exolit®.•Distributed activation energy model was developed to describe slow pyrolysis kinetics.•The addition of Exolit® delayed the time evolution of methylmethacrylate from PMMA.•The yield of methylmethacrylate from fast pyrolysis decreased by 10−20 wt.% with Exolit® addition.•Contracting cylinder and Avrami-Erofeev models describe the fast pyrolysis kinetics.
