| Abstract | ||
| The new schiff base complex: Chloro- (bis (salicylaldehyde) ethylene diiminato) aqua manganese (III) is synthesized and characterized. It is used as thermal initiation in radical polymerization of styrene at 80 c◦ in dark without inhibition and retardation complication, and the rate of polymerization is directly proportional to the squre root of initiator concentration [I]1/2 . gravimetry technique is used for deteremination of the rate polymerization, and viscometery is used for determination of average of polymerization. The uv- visble spectrophotometry is used to determine the rate constant of initiator decomposition (ka). The value of the kinetic parameter ratio kp / kt 1/2 (Where kp & kt are the rate constants, propagation and termination respectively). | ||
