| Abstract: | Free-radical solution copolymerization of acrylic acid（AA） and acrylonitrile（AN） was carried out in cyclohexane using azodiisobutyronitrile（AIBN） as initiator.The effects of monomer concentration,initiator,reaction temperature and time on copolymerization were studied.The polymerization rate was determined from conversion,the structure and properties of polymer were characterized by IR and TG.It has been show that the ideal condition of the copolymerization should be controlled the concentration of AIBN of 1 %,at 70 ℃ with reaction time about 24h when the concentration of monomer was 22 %. |
