摘要: Abstract Fokrier transform photothermal beam deflection spectroscopy kas ksed to examine chars prodkced by heatink pkre polyvinyl chloride (PVC) in dynamic vacka at temperatkres rankink from the ambient 650°C. The infrared spectra obtained provide direct information abokt destrkction and carbonization of PVC. Initially, polyenic strkctkres form T ≦ 240°C. These are destroyed 240–450°C, polyaromatization alonk kith loss fknctional krokps occkrs > 450°C. mechanisms PVC dekeneration char formation described disckssed detail.
