Abstract
Two different types of polymeric surfactants (nonionic and cationic) were prepared based on homopolymerization of
triethanolamine acrylate monomer. Triethanolamine acrylate monomer obtained by esterification of acrylic acid with
triethanolamine and polymerized giving compound named (PTEAA). The nonionic polymeric surfactants named
(PTEAAN.10 and PTEAAN.12) were prepared by esterification of PTEAA with Decanoic acid and Lauric acid. The
cationic polymeric surfactants named (PTEAAC.10 and PTEAAC.12) were prepared by quaternization of PTEAA with
1-bromodecane and 1-bromododecane. The structure was confirmed by FTIR, 1H-NMR, 13C-NMR spectroscopic data,
and GPC. The surface tension of the aqueous solution by these surfactants was measured at different temperatures. The
critical micelle concentration (CMC), effectiveness (π›‘πœπ¦πœ) , minimum surface area (𝐀𝐦𝐒𝐧), and maximum surface excess
(πšͺ𝐦𝐚𝐱) were calculated. The surface activity measurements showed their high affinity towards adsorption, micellization
and their good surface tension reduction. The thermodynamic parameters of micellization (βˆ†π†π¦π’πœ

,βˆ†H°mic,βˆ†S°mic) and
adsorption (βˆ†π†πšππ¬
°
,βˆ†H°ads,βˆ†S°ads) showed their tendency towards adsorption at the interfaces and also micellization in
the bulk of their solutions. The obtained data give the opportunity to use these surfactants as corrosion inhibitors in
petroleum fields
