POLYMERIC SURFACTANTS

摘要

Amide surfactant compound of the formula (I): R<1>-CO-NR<2>R<3>, where R<1> is a polymeric hydrophobe group; R<2> is a group CH2-(CHOR<4>)n-CH2OR<4> where n is from 3 to 6 and R<4> is hydrogen, C1 to C6 alkyl or a saccharide residue, containing at least 2 free hydroxyl groups; and R<3> is hydrogen, C1 to C22 hydrocarbyl, substituted alkyl, or R<3> is independently as defined above for R<2>, are useful as emulsifiers and/or stabilisers for water in oil emulsions, or as dispersants for solids in aqueous or non-aqueous liquids. Particular end use applications include as emulsifiers, stabilisers or dispersants in making polyacrylamide, particularly for water treatment, by inverse emulsion polymerisation; emulsion explosives; personal care compositions including an aqueous phase dispersed or emulsified in an oil phase; agrochemical emulsions and concentrates, and cutting fluid emulsions and concentrates.
