Syntheses, characterization and study of use of manganese (III)‎ schiff-base complex as thermal initiation in radical polymerization of styrene

الملخص EN

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).
