摘要:
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 dispersant.
摘要:
The present invention provides a non-aqueous composition containing a particulate solid, an organic medium and a polyurethane dispersant having laterally attached pendant groups with tertiary amine group(s), an essentially linear backbone and laterally attached solvent-solubilising side chains of a polyester or polyether including mixtures of such side chains.
摘要:
Polymeric urethane dispersants with solubilizing polymer chains and with reactive carbon to carbon double bonds are described. The reactive double bonds facilitate molecular weight build-up of the dispersant on dispersed particles (enhancing colloidal stability) or enhance the ability of the dispersants to be crosslinked into a matrix material.

摘要:
The invention relates to a graft copolymer with a polyester side chain and at least one quaternised 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.
