Abstract
Thermal stability of maleic anhydride-vinyl acetate copolymer was studied in a range of temperatures from 150 to 200deg;C by a flow method. Above 150deg;C the copolymer begins to decompose. Main volatile product is acetic acid, which amounts to weight loss. By assuming first order reaction with respect to weight loss, activation energies were determined as 42.6 kcal/mol in nitrogen and 28.4 kcal/mol in air. Analysis of the decomposed copolymer shows that both double bond and cross-linkage are formed more easily in nitrogen than in air, and that epoxy groups, however, are formed only in air. A degradation mechanism is suggested.
