In our previous work N-phthalimidomethyl methacrylate (NPMMA) monomer was prepared through the reaction of Nhydroxymethyl phthalimide with methacrylic acid in the presence of N, N-dicyclohexylcarbodiimide (DCCI) as a condensing agent. Then a new series of copolymers containing imidazole have been synthesized through the reaction of NPMMA monomer with 1-vinylimidazole (VIM) in the presence of benzoyl peroxide as initiator. The copolymer composition was determined by 1 H NMR spectroscopy and the values of monomer reactivity ratio (r1= 0.756, r2= 1.033, and r1r2= 0.781) were calculated through Fineman Ross and Kelen-Tüdös methods. Conversion of copolymers to surfactants was achieved through quaternization of the imidazole nitrogen with dimethyl sulphate. The chemical structure of the produced monomer, copolymers, co-polymeric surfactants was confirmed by spectroscopic tools. The surface properties included surface tension, foaming power, emulsion stability, critical micelle concentration (CMC) have been measured in aqueous medium by traditional procedures. Also the different air/ water interface parameters including effectiveness (πcmc), efficiency (Pc20), maximum surface excess (Γmax) and minimum surface area (Amin) were also recorded. Moreover, the biodegradability for these cationic surfactants has been investigated and their D % was ranged from 67 to 100 %.

Polymeric complexes, especially metal‐containing polymers, possess aggregated medical applications, especially as antibacterial and antifungal agents. This work describes a facile procedure for producing a series of novel copper and nickel complexes of poly(2‐hydroxyphenyl methacrylamide) and poly(2‐carboxyphenyl methacrylamide). The polymeric ligands were synthesized through a multistep procedure. Firstly, 4‐formylphenyl methacrylate was constructed by acylating 4‐hydroxybenzaldehyde with methacryloyl chloride. Then, polymerization of the as‐prepared monomer to obtain poly(4‐formylphenyl methacrylate) using benzoyl peroxide as an initiator. Thirdly, the polymeric ligands PL1 and PL2 were achieved via exchange reactions between poly(4‐formylphenyl methacrylate) and o‐aminophenol and anthranilic acid, respectively. Consequently, the two ligands were reacted with copper and nickel acetates to afford four target complexes (Cu‐PL1, Ni‐PL1, Cu‐PL2, and Ni‐PL2). By FT‐IR, 1HNMR, UV‐visible, and TGA analyses, the structures of PL1, PL2, and their complexes were investigated. Furthermore, the geometries of PL1, PL2, and their complexes were reported through a molecular modeling to investigate some interesting parameters such as the bond length, bond angle, charge on the atoms, the HOMO and LUMO using the Material Studio program. The calculation results illustrated that octahedral geometries are proposed for the synthesized metal complexes. The reported antimicrobial efficiency showed a strong potency for most synthesized compounds against the selected microbes, especially compounds Cu‐PL1 and Cu‐PL2 which are more effective than the standard against Candida albicans.
