Abstract

The copolymerization of acrylamide (AM) with N.N'-methylenebisacrylamide (Bis) in the aqueous solution has been studied. All the experimental results showed that the reactivity of Bis is obviously greater than that of AM. The monomer reactivity ratios determined by gas-chromatography method are 0.117 and 5.756 for AM and Bis respectively. The effects of the concentration of oxidation-reduction initiator and the reaction temperature on the rate of the copolymerization have been investigated with ultraviolet spectroscopy

the initial rate of the copolymerizationis proportional to the 0.66 power of [(NH4)2S2O8] and 0.55 power of [NaHSO3]

and the apparent reactive energy of this copolymerization is 37.1KJ/mol.
