Sequence of reactions in thermooxidative degradation of polyacrylonitrile and of acrylonitrile-methyl acrylate copolymer (in Russian)
Despite the considerable number of studies of thermooxidative degradation of polyacrylonitrile (PAN), the question of the sequence of reactions involved is not completely clear. The mechanism of action of comonomer units on the course of degradation in acrylonitrile copolymers has been studied very little, apart from initiation of degradation by comonomer units of the carboxylic acid type. The question of participation of comonomer units of the acrylate, methyl acrylate, etc., types remains open. Since most commercially available PAN fibers contain units of this type, study of the thermal stability of acrylonitrile-methyl acrylate (AN/MA) copolymer is of considerable practical importance. Accordingly, the purpose of the present work was to establish the sequence of thermooxidative degradation reactions and to elucidate the influence of comonomer units of the ester type on the course of these reactions.
