Исследование влияния условий синтеза на основе дикарбоновых кислот

Abstract

Among functional acrylamide-based copolymers, those with acids containing two carboxyl groups are of particular interest: they can impart high hydrophilicity, buffering properties, ionic activity and pronounced colloid-chemical characteristics to materials. One of the promising monomers of this class is itaconic acid (IA), which has pronounced reactivity and structural features that allow stable ionogenic chains to form during copolymerization with acrylamide. Owing to its biocompatibility and biodegradability, itaconic acid is already used in medicine, agriculture and environmental technologies. This paper presents the results of a study of the synthesis of water-soluble copolymers of acrylamide with itaconic acid. Particular attention is paid to comparing the colloid-chemical properties of the obtained samples with those of previously studied copolymers of acrylamide and maleic acid under identical synthesis and modification conditions. The comparative approach makes it possible to evaluate the effect of the nature of the comonomer on the main structural and functional characteristics of the copolymer and to select the most effective system for further use as structure-forming and water-retaining reagents.
