| Abstract: | Free radical solution copolymerization of methyl acrylate and acrylonitrile is carried out in DMSO at definite temperature using azodiisobutyronitrile(AIBN) as the initiator.The effect of concentration of monomer and initiator,reaction temperature and time on copolymerization are studied.The conversion rate of the polymerization and the relative molecular weight of the product are determined by weight method and Ubbelodhe viscosimeter.It has been shown that the ideal copolymerizing condition is the concentration of AIBN 1% at 60℃ with reaction time about 30 h when the concentration of monomer is 25%. |
