COPOLYMERS CONTAINING POLYALKYLENE OXIDE GROUPS AND QUATERNARY NITROGEN ATOMS Russian patent published in 2020 - IPC C11D1/02 C11D3/26 C11D17/00 C08F220/28 

FIELD: chemistry.

SUBSTANCE: present invention relates to a copolymer. Said copolymer contains, in a copolymerized form, from 60 to 99 wt % of at least one monoethylenically unsaturated polyalkylene oxide monomer of formula , where X is -CO-, Y is -O-, R¹ is hydrogen or methyl, R² is identical or different alkylene radicals with 2–6 carbon atoms, which can be ordered blockwise or statistically, R³ is hydrogen or alkyl with 1–4 carbon atoms, n is integer from 25 to 75; and from 1 to 40 wt % of at least one quaternized nitrogen-containing monoethylenically unsaturated monomer containing formula , where R is alkyl with 1–4 carbon atoms, X^-—alkyl sulphate with 1–4 carbon atoms, alkylsulfate with 1–4 carbon atoms. Copolymer has average molecular weight M_w>100,000.

EFFECT: development of polymer detergents, characterized by a set of favorable consumer properties, in particular, improved primary and secondary detergency, which can be easily and stably added to preparations of solid and liquid agents for machine dish washing, hand washing of ware and cleaning of solid surfaces.
