Özet

γ-Ray-initiated copolymerization of acrylamide and maleic anhydride was studied in the solid state at 25°C. The polymeric product was found to be free of the homopolymers. The mole fraction of acrylamide in the monomer mixture was varied from 0.33 to 0.91. The copolymerization reached a 'limiting conversion' the value of which was dependent on the composition of the monomer feed. The mole fraction of maleic anhydride in the copolymers did not exceed 0.50 and the compositions of copolymers obtained from acrylamide-rich mixtures were virtually the same as those from the monomer feed compositions. The alternating tendency of maleic anhydride was evidenced by the variation of the copolymer compositions and the consumption rates of the individual monomers. © 1990.
