摘要: Laser-pyrolysis; time-of-flight mass spectrometry has been applied to the study of rapid thermal degradation polymethymethacrylate (PMMA) and rigid polyurethane foams. The heating rate little influence on mechanism PMMA degradation. In both laser low experiments, monomer was major pyrolysis product. Laser foams resulted in evolution polypropylene glycol as species together with molecular weight such CO2 etc. It is considered that its further decomposed act fuel for flame a real fire situation. ratio evolved gases decreased increase isocyanate index. This associated improvement resistance at high
