Novel Applications of Some Organic Copolymers Derived From Phenolic and Nitrogen-Containing Compounds- A Review

Abstract

A variety of organic copolymers have been synthesized from phenolic compounds like p-Hydroxybenzoic acid, p-Hydroxybenzaldehyde, p-Hydroxyacetophenone, and also from nitrogen- containing compound like anthranilic acid, aniline, urea, biurate. These copolymers have been studied for various properties like thermal behavior, kinetic parameters, antimicrobial screening, ion-exchange study, polymer composites, photoluminiscence etc. Kinetic parameters of the copolymers derived from phenolic and nitrogen-containing compounds have been studied using Freeman-Carroll (FC) and Sharp-Wentworth (SW). Based on TGA, thermal stability and decomposition temperature have been studied for the copolymers and composites. Higher thermal stability for copolymer composites has been found as compared to the copolymer because the composite has a high activation energy and more residue left out at the end of the decomposition process. The metal ion uptake capacity of the copolymer have been studied by using the batch equilibrium method and is useful for wastewater treatment. The antimicrobial activity of the copolymers have been studied using the agar diffusion method. Polymer composites have been made from copolymers using an ultra-sonication process and exhibit excellent properties in metal ion uptake for wastewater treatment. The present review paper involves the study of novel applications of the copolymer resins derived from phenolic compound and nitrogen-containing compound.
