Polymerization of cyclohexanone formaldehyde resin modified with carbazole‐9‐carbonyl chloride

Abstract

Purpose – The purpose of this paper is to synthesise cyclohexanone formaldehyde resin (CFR)‐modified carbazole‐9‐carbonyl chloride (CzCl) via hydroxyl groups of CFR. This carbazole‐modified resin (Cz‐CFR) comonomer was characterised by common techniques such as UV, NMR, FTIR, fluorescence spectrophotometer, and scanning electron microscopy. The oxidative and electrochemical polymerisation of CzCl‐modified cyclohexanone formaldehyde resin (Cz‐CFR) were carried out.Design/methodology/approach – Cz‐CFR comonomer was synthesised by the esterification reaction of CzCl and hydroxyl groups of CFR. Then, for the chemical polymerisation, ceric ammonium nitrate (CAN)/DMF solution was added to the comonomer/DMF solution. The precipitate was filtered, washed with chloroform and dried. For the electrochemical polymerisation, potentiodynamic electrodeposition of Cz‐CFR comonomer in dichloromethane on to Pt was carried out.Findings – The concentration effect of CAN and Cz‐CFR on the conductivity, yield, solubility and T...
