Abstract
Irradiation of sodium allylsulfonate in aqueous solution at high pressure (up to 9000 kg/cm/sup 2/) gave a deliquescent white powder which is insoluble in organic solvent. The product was addition polymer of allylsulfonate from the high-resolution NMR and infrared spectra. The rate of polymerization was proportional to the third and second powers of monomer concentration in the initial and later stages, respectively. From the high dependence of the rate on monomer concentration, the reaction was deduced to proceed in an associated monomer or micelle. The rate of polymerization was increased by addition of sodium chloride. The G value for monomer consumption was about 10/sup 4/ at high pressure, which suggests that the degradative chain transfer is not important in the polymerization. Overall activation volumes were -7 and -5 ml/mole in the initial and later stages, respectively.
