The degradation mechanisms of polybutylacrylate (PBA) under the various pyrolysis temperatures were studied by means of pyrolysis-gas chromatography. When the degradation of PBA is performed at the pyrolysis temperature of 530°C or below it, a little yield of monomer (butylacrylate) was observed in addition to the hydrocarbons and acrylic acid which were formed from the competitive reactions of chain scissions and elimination of butene. Observing the relationship between relative yield of products and pyrolysis temperature from PBA, it was suggested that the mechanisms of the thermal degradation of PBA vary with the pyrolysis temperature used. And also we discussed the analysis of butylacrylate-acrylonitrile copolymers by use of the relative yield of the acrylic acid and acrylonitrile.
