METHOD OF OBTAINING POLYMER IONIC IMIDAZOLIUM COMPOUNDS Russian patent published in 2014 - IPC C08G12/06 C08G73/06 

FIELD: chemistry.

SUBSTANCE: invention relates to method of obtaining polymer compounds, containing imidazolium ionic groups, which can be used as dispersers. Method consists in performing interaction of α-dicarbonyl compound, aldehyde, at least, one amino compound, and hydrogen acid, α-dicarbonyl compound representing compound of formula (I) R¹-CO-CO-R², in which R¹ and R² independently on each other represent hydrogen atom or organic residue with 1-20 carbon atoms. Aldehyde represents aldehyde of formula (II): R³-CHO, in which R³ stands for hydrogen atom or organic residue with 1-20 carbon atoms. Amino compound has, at least, two primary amino groups, and represents alkylene diamine with 2-20 carbon atoms, or aromatic diamine, or triamine. Hydrogen acid represents carboxylic acid, sulfonic acid, phosphoric acid or phosphonic acid, and acid groups of sulfonic acid, phosphoric acid or phosphonic acid can be partially etherified. Carboxylic groups of α-dicarbonyl compound and aldehyde, in case of necessity, can be present in form of hemiacetal, acetal, respectively, hemiketal or ketal groups.

EFFECT: invention makes it possible to simplify technological process and increase output of polymer compounds.
