The thermoanalytical, infrared and pyrolysis-gas chromatography-mass spectrometric sifting of poly (methyl methacrylate) in the presence of phosphorus tribromide

چکیده
The behaviour of poly(methyl methacrylate) was examined in the presence of phosphorus tribromide (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 temperature zones were identified for stabilization of the system. New products were found and mechanisms of their formation were proposed. Pyrolysis of the blends was also carried out at different temperatures to ascertain the nature of interaction between the constituents of the system.
