The present work a.med to synthesize a.new interesting series of thia.ole ba.ed polya.ides conta.ning dia.ylidenecyclohexa.one moiety 5a.5f using low tempera.ure solution polycondensa.ion technique. The new polymers were synthesized by the rea.tion of thia.ole ba.ed monomer na.ely, bis（2-a.inothia.ol-4-ylbenzylidene）cyclohexa.one 3 with different a.ipha.ic a.d a.oma.ic dia.id chlorides using NMP, a.d in the presence of a.hydrous Li Cl a. ca.a.yst. a.ipoyl, seba.oyl, oxa.oyl, terephtha.oyl, isophtha.oyl dichlorides a.d biphenyl dica.bonyl dichloride were used a. dia.id chlorides. The structure of the model compound 4 a. well a. the new polymers wa. confirmed by correct elementa. a.d spectra. a.a.yses. The therma. properties of those polymers were eva.ua.ed by TGa.a.d DTG mea.urements a.d correla.ed to their structura. units, beside X-ra. diffra.tion a.a.ysis, solubility a.d viscometry mea.urements. The inherent viscosities for the synthesized polymers were in the ra.ge 0.6–1.03 d L/g. On the other ha.d the corrosion inhibitive properties of monomer 3 a. well a. polya.ides 5d a.d 5f a. selected exa.ples were ca.ried out on ca.bon-steel in 0.5 mol/L H2SO4 a. 40 °C. The ca.cula.ed inhibition efficiency（IE%） for polymer 5d wa. in the ra.ge（82 ± 6）% in a.l selected concentra.ions. The best va.ue of IE% wa. obta.ned a. 1 mg/L to rea.h 98.24% for polymer 5d a.d a. 0.5 mg/L to rea.h 87.75% for polymer 5f.
