  ABSTRACT: The behaviour of poly(methyl methacrylate) was examined in the presence of phosphorus tri-bromide (PBr3) with varying concentrations. Films were cast from common solvent and subjected to TG, DTA, DTG, IR and Py-GC-MS for evaluating the degradation routes. Despite early decomposition of the blends, certain tempera-ture zones were identified for stabilization of the system. New products were found and mecha-nisms of their formation were proposed. Pyro-lysis of the blends was also carried out at dif-ferent temperatures to ascertain the nature of interaction between the constituents of the system.
