The triphenylphosphine (TPP) initiated polymerization of methyl methacrylate (MMA) in dimethyl sulphoxide (DMSO) has been studied. The polymerization was found to be solvent-sensitive and could be accelerated by Lewis acids like Fe 3Γ· . Kinetic studies showed that the propagation was free radical in
Visible absorption spectra and the molar conductance curve for CoCI, in dimethyl sulphoxide (DMSO) have been determined and are analyzed in terms of the nature of ionization equilibria set up in the respective solutions.

Visible absorption spectra of the CuCl+ and CuCl; complexes in dimethyl sulphoxide (DMSO) are derived from an auxiliary study of the Cu(CIO,), + Et,NCI mixed solutions of variable chloride concentration. The second step association equilibrium CuCI+ + Cl-= CuCl; is then shown, from the visible absor
