Abstract: The radiation induced precipitation copolymerization of acrylonitrile(AN)/methyl acrylate(MA)/itaconic acid(IA)in certain solvents was studied.High molecular weight AN/MA/IAcopolymer(Mw≥5×105)fitted for high property carbon fibre has been synthesized.The effects of dose, dose rate, monomer concentration and the composition of mediums on the molecular weight of copolymers have been investigated to determine the best polymerization conditions.The system with 25%monomer(AN/MA/IA=97/2/1), 30%DMFand 45%H2Ois a favorable one, D=22 Gy/min, R=2.2 kGy are the reasonable radiation conditions.

Key words: Polyacrylonitrile, Supper-high molecular weight, Radiation induction, Precipitation polymerization
