dc.description.abstractMetal (styrene-methyl methacrylate) copolymers were obtained by radical polymerization with azodiisobutyronitrile.
dc.description.abstractThe thermal stabilities of the metal copolymers (PS-PMMA) have been studied by thermogravimetry (TG) between 25 and 550-degrees-C under nitrogen flow. The kinetic data thus obtained show that the thermostabilities decrease in the order: Pd-(PS-PMMA) > Au-(PS-PMMA) > Ge-(PS-PMMA) > Bi-(PS-PMMA) > Sn-(PS-PMMA) > Cu-(PS-PMMA) > In-(PS-PMMA) > Ga-(PS-PMMA), suggesting that thermal stability is dependent upon the metal incorporated in the backbone. The order of reaction from thc thermal decomposition of these metal copolymers was found to be zero. The pre-exponential factor, the reaction order and the activation energy of the decomposition for metal (styrene-methyl methacrylate) copolymers have been determined and the reactions found to be zero order in most of them.
