Research Abstract

Organo-fluoride polymers,major fluorine chemicals are subject to pyrolysis,and their degradation products were analyzed by thermo-gravimetry, GC/MS, LC/MS, and electron micro-analyzer with EDX. Volatile compounds with low molecular weight,medium volatile compounds and waxy compounds with micron/nano particles were identified and their potential environmental risk was considered.
