AQUEOUS SOLUTION OF (METH) ACRYLIC FLUID COMB-BRANCHED POLYMERS HAVING SOLIDS CONTENT GREATER THAN 60%, METHOD OF MANUFACTURE AND USE AS PLASTICISERS Russian patent published in 2016 - IPC C04B24/26 C08F220/26 C04B28/28

Abstract RU 2586972 C2

FIELD: chemistry.

SUBSTANCE: invention relates to an aqueous solution of comb-branched polymers having a (meth)acrylic backbone chain, functionalised side chains containing hydrophilic alkoxy- or hydroxypolyalkylene glycol functionality as indicated in formula. Invention also relates to a method of producing said solutions, as well as to use thereof as plasticising additive and compositions containing same, based on hydraulic binder.

EFFECT: said solution remains stable and is recycled at levels of content of dry solid substance, higher than 60 % of its weight.

15 cl, 2 tbl
