Synthesis, Characterization & Analytical study of anew Schiff base derive from substituted aniline and Their Complexation with Zn+2 , Cu+2 & Cd+2 ions ,Copolymerization and their biological study.

Some new Schiff base compounds were prepared through the reaction between salicyldehyde and subsituted aniline .These compounds were characterized by FTIR &CHN analysis .Complexation of these Schiff base with some transition metal nitrates in alcoholic solution were done and the result shown that the M:L ratio is (1:2). On other hand these compounds were polymerized via condensation polymerization with resorcinol and formaline solution in basic medium .,their ability for complexation with Zn ,Cu &Cd ions were examined by using Flame photometry the result shown that the ability of metal complexation in the order of Zn+2 >Cu+2 >Cd+2 .Thermal studies of these copolymers were done using TGA and DSC techniques , The result shown that these copolymers have good thermal stability .Finally the biological studies showed no activity towards two kinds of bacterial while all the prepared Schiff base gave positive test .
