الملخص EN

During this resceach, some chemical modifications have been done on pplyfstyrenfe-butadierte] rubber.

Obviously, chcmical modified polymers have ne'w different chemical and physical properties with expected new applications.

The first chemical modification done are introduce of (-NO2) group into poly|styrene-butadienc], then reduction of this group to (-NM2) using S/Na2S.xH20 to obtain poly[(p-aminostyrene)-butadiene].

When primary amine group allowed to react with anhydrous phthalic acid we obtained the polymer which contain amic acids, then last polymer was dehydrated using strong dehydrating agents, N,N-dicyclohcxylcarbodimidc (DCC), and trifloroacctic anhydride-tricthylaminc, vvc obtained polymer contain pending isoimide, then the isomerization using heat and acid or base, but we found that the polymer was resist to rearrange to corresponding imide, and when the amic acid polymer was allowed to react with a mixture of sodium acetate - acetic anhydride we obtained imide with good yield.

Structures of all prepared polymers were confirmed by the measurement of softing points, viscosity, solubility in different solvents, FTIR, UV, H-NMR spectroscopy, thermalstability study using thermogravimetry analysis technique TGA, and some specific tests.
