Synthesis and characterization of poly [N-acryl-N-sulfonic acid-N yL-2-substituted-4-oxo-thiazolidine] maleic and succinic di imide

Abstract EN

In the present investigation, new polymers of Poly [ N-acryl - N - sulfonic acid - N\ yL-2- substitute-4-oxo - thiazolidine ] Maleic and Succinic diimide were synthesized by seven steps; first step includes esterification of different cyclic anhydride, using one mole of absolute methanol in the presence few drops of conc.

H2SO4, yielded mono group ester [I] , which was reaction with thionyl chloride to give ester acid chloride [II] .Then reacted with sulfanilic acid to product compound [III] , which was condensation with hydrazine hydrate to give acid hydrazide [IV] .

The new different Schiff bases [V-VIII] were synthesized by reaction of acid hydraizide with different (aliphatic and aromatic) aldehyedes and ketones in the presence of glacial acetic acid.

Thiazolidine-4-one derivatives [IX-XII] have been obtained from the addition of 2-mercapto acetic acid to Schiff bases and the final step was added poly acryloyl chloride to product polymers [XIII-XVI] .

There chemical structures have been confirmed by melting points , FTIR,1HNMR and 13C-NMR (some of them).

All the synthesized polymers were characterized by FT– IR spectra, softening points and TGA,DTG (some of them).
