AbstractThe 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).
