Thermal decomposition of flame retardant acrylonitrile copolymers investigated by direct pyrolysis in the mass spectrometer

The thermal behaviour of copolymers of acrylonitrile containing vinylidene chloride (VC2), 1‐bromo‐1‐chloroethylene (VCB), vinyl bromide (VB) units and Sb2O3, was investigated by gradually increasing the temperature of a polymer sample placed in the ion source of a mass spectrometer (MS). The result...

Description
Summary:The thermal behaviour of copolymers of acrylonitrile containing vinylidene chloride (VC2), 1‐bromo‐1‐chloroethylene (VCB), vinyl bromide (VB) units and Sb2O3, was investigated by gradually increasing the temperature of a polymer sample placed in the ion source of a mass spectrometer (MS). The resulting pyrolytic processes (time‐temperature resolved) were analyzed by detecting the volatile decomposition products formed. Sb‐halogenated species were detected in the mass spectra of the thermal decomposition products of the copolymers, and their presence is interpreted as the result of antimony‐halogen hydracids interactions during the pyrolysis.
