... black Phthalocyanine blue Permanent violet Water-based Colouring strength Viscosity Dispersions pigments Surfactants The ¹H NMR spectra of SMA, PEA and the SMA-g-PEA hyperdispersant are displayed in Figure 4 . In the test, deuterium acetone was used as solvent...

... operating parameters such as probe diameter and use of surfactants on the physical properties of dispersion and the colour strength have been investigated. Calculations for the energy requirement for two approaches have also been presented. Findings – The use of sodium dodecyl sulphate and Tween 80...

...‐SiO₂ oxide composites impregnated with natural latex rubber were established. The formation and impregnation the ZnO‐SiO₂ oxide composites were made to occur simultaneously. Design/methodology/approach The influence of non‐ionic surfactants added during the precipitation process...

...M.M. Azab; S.K. Bader; A.F. Shaaban A novel two series of self‐sequestering surfactants have been prepared by the reaction of itaconic acid, phthalic anhydride, citric acid with oxypropylated 1,4‐butane diol and oxypropylated 1,6‐hexane diol. The structure features of these surfactants have been...

...W.I.A. El‐Dougdoug; A.A. Mahmoud A series of anionic copolymeric surfactants based on n‐octylacrylate ester (M₁) as hydrophobe, and sulfated products of oxypropylated allyl alcohol (M_{S1−S2 and S3}) as hydrophiles, were prepared by copolymerization of n...

...W.I.A. El‐Dougdoug; M.M. Azab A series of polymeric surfactants based on butylacrylates (M₁) as hydrophobe, and amide oxime of oxypropylated acrylates (M_{2‐4 and 6}) as hydrophiles, were prepared by copolymerization of butyl acrylate (M₁) and amide oxime...

...M.M. Azab; S.K. Bader; A.F. Shaaban Four series of nonionic copolymer surfactants have been prepared by the free radical copolymerizations of dioctyl itaconate (DOI) with dioxypropylated itaconic acid. Copolymerization reactions were carried out in solution at 70°C using 1mol. percent...
