Abstract
The thermal behaviour of acrylamide-maleic anhydride copolymers was studied by thermogravimetric (TG and DTG) analysis. The obtained data permitted the calculation of activation energies and reaction orders of the decomposition steps by the Coats-Redfern and Freeman-Carroll methods. Thermal analysis shows four distinct peaks in the case of polyacrylamide and AA∶MA (7∶1) copolymer and only three for AA∶MA (1∶1) copolymer. In AA:MA (1∶1) copolymers intermolecular imidization occurs only and thermal degradation is influenced more by the anhydride groups which are equal in number with the amide ones.
