    Synthesis and characterization of novel polystyrene-silica composites containing azomethine
    (Elsevier, 2021) Nartop, Dilek; Kazak, Cigdem
    Herein, four novel polystyrene / silica composites containing azomethine (Si-PSNO2, Si-PSH, Si-PSCl, Si-PSCH3) were reported. For this purpose, polymers including azomethine (PSNO2, PSH, PSCl, PSCH3), one of which is novel (PSNO2) were obtained from condensation reaction between 4-benzyloxybenzaldehyde with 2-aminophenol and its derivatives. Then, these polymers were immobilized on 3-chloropropyl functionalized silica gel to obtain polymer / silica composites. The structures of novel composites were characterized by various spectroscopic techniques (IR, GPC, TG-DTA, SEM-EDX, EA, ICP-MS, optical profilometer). (C) 2020 Elsevier B.V. All rights reserved.
