説明
The copolymerization of acrylonitrile (AN) with sodium methallyl sulfonate (SMAS) in dimethyl sulfoxide (DMSO) at pH 7, in aqueous DMSO solution (6% H20) at pH 7, in DMSO at pH 1.5, in aqueous solutions at pH 7 and at pH 1.5 has been investigated. Monomer reactivity ratios at 45°C for AN and SMAS were found to be r1=0.45, r2=1.50 in DMSO at pH 7; r1=0.55, r2=1.20 in aqueous DMSO; r1=0.75, r2 =1.30 in DMSO at pH 1.5; r1=0.85, r2=0.50 in aqueous solution at pH 7; r1=1.10, r2=0.70 in aqueous solution at pH 1.5. From these values Price's Q and e values, for SMAS were calculated, and it was found that they are 0.63 and 0.57 in DMSO at pH 7, and O.51 and O.55 in aqueous DMSO, 0.67 and 1.04 in DMSO at pH 1.5, O.23 and O.28 in aqueous solution at pH 7, and 0.27 and 0.69 in aqueous solution at pH 1.5 respectively. The large differences in reactivity of SMAS may be attributed to the different electron distributions in SMAS in each solvent which are caused by poor solvating power of dimethylsulfoxide and by the addition of protons. Homopolymerization of SMAS shows first-order dependence on the initiator concentration, and this is attributed to degradative chain transfer of SMAS. The rate of copolymerization of AN and SMAS decreases with increasing SMAS content. It has been found that there is a peculiar effect in the range of 8-12 mole % of SMAS monomer feed in aqueous solution which is in the transition state from homogeneous t heterogeneous phase.
