The present invention provides a dispersant of Formula (1) and salts thereof Formula (1) wherein E is R or R-NR'-T-; R is H or C1-5o-optionally substituted hydrocarbyl; R' is a residue of an optionally substituted alkyl (meth)acrylate or (meth)acrylamide, or a residue of an epoxide, or a C1-8- optionally sub...

The invention relates to a composition containing a particulate solid, a plastic material and a compound. The invention further relates to novel compounds, and the use of the coupling agents.

The invention relates to a composition containing a particulate solid, plastic material (such as a vinyl chloride polymer), and a compound containing an acidic group.

The invention relates to a graft copolymer with a polyester side chain and at least one quatemised tertiary amine group. The tertiary amine may be aliphatic, aromatic or heterocyclic. The invention further relates to the use of the compound as a dispersant, particularly for pigments.

The present invention provides a dispersant and compositions thereof. The dispersant is a residue of a non-aromatic hydrocarbyl substituted carboxylic acid containing three or more acid groups (A), wherein the dispersant may be represented by the Formula and salts thereof: [U-(Y)X-T-N(R1)c-A]d-Z(Q1)j-We, wherein the...

The present invention provides a composition comprising (i) a participate solid; (ii) an organic medium; and (iii) a salt of a hydrocarbyl-substituted acylating agent. The invention further provides for the use of the composition in various applications including paints, inks or mill bases. ...

The invention relates to a composition containing a particulate solid, an organic or aqueous medium, and a copolymer containing less than 25 mol % of residues of monomers comprising a dicarboxylic acid, or anhydride thereof. The invention further relates to novel copolymers, and the use of the copolymers as a disper...
