Abstract

The oxidative thermal degradation of acrylic–SO₂ copolymers was investigated by TG, DTG, and DTA. Their thermograms show that the copolymers decompose in several reaction stages with different weight loss, accompanied by several exo‐ and endothermic effects. Acrylonitrile–SO₂ and methacrylate–SO₂ copolymers exhibit a two‐stage thermal decomposition, whereas the polysulfones of the acrolein–SO₂ and acrylamide–SO₂ systems decompose in four stages. Both the number of SO₂ units present in the copolymer and the polarity of the pendant group on the organic monomer have some effect on the thermal stability and the glass transition temperature of the polymers. © 1993 John Wiley & Sons, Inc.
