ALCOHOXYLATED POLYETHYLENEMINE WITH LOW MELTING TEMPERATURE Russian patent published in 2018 - IPC C08G73/02 C08G65/26 

FIELD: chemistry.

SUBSTANCE: invention relates to water-soluble alkoxylated polyalkyleneimine or polyamine and to process for its preparation. Alkoxylated polyalkyleneimine or polyamine has the general formula I, in which R is identical or different linear or branched alkylene radicals having from 2 to 12 carbon atoms or an etheralkyl unit; B is the elongation of alkoxylated polyalkylenimine by branching; E is an alkyleneoxy unit of formula II, in which R¹ is 1,2-propylene, 1,2-butylene and / or 1,2-pentene; R² is hydrogen and / or alkyl of 1 to 22 carbon atoms and / or aralkyl of 7 to 22 carbon atoms; y and z are each from 0 to 150, m is an integer ranging from 5 to 18; n is an integer having a value in the range from 1 to 5; p is an integer having a value in the range from 2 to 14. Process for the preparation of the alkoxylated polyalkyleneimine or polyamine is that the polyalkyleneimine or polyamine first reacts with ethylene oxide, then with propylene oxide or butylene oxide and then with ethylene oxide. I II.

EFFECT: invention makes it possible to prepare an alkoxylated polyalkyleneimine which is liquid at room temperature or below it and has low melting point.
