The thermal degradation of copolymers of phenyl methacrylate (PMA) and
styrene (ST) was studied by thermal volatilisation analysis (TVA), th
ermogravimetric analysis (TGA) and differential thermal analysis (DTA)
. The main pyrolysis products have been identified and the characteris
tic of the reactions discussed. Mechanisms have been proposed to accou
nt for the products formed. (C) 1996 Elsevier Science Limited
