Abstract:
Kinetics of 2,2′-azobisisobutyronitrile initiated polymerization of styrene in N,N-dimethylformamide (DMF) were investigated in the presence of dichloro bis(N,N-dimethylformamide)copper(II) complex. The complex was prepared in situ by mixing tetrakis(N,N-dimethylformamide)copper(II) perchlorate with LiCl in the molar ratio of 1:2. The equilibrium constant for was calculated by the limiting logarithmic method as 1.07 × 1010 l2 mol?2. The velocity constant at 60 for the interaction of polystyryl radical with Cu(DMF)2Cl2 is 2.16 × 104 l. mol?1 sec?1.
