Dispersant composition

摘要

The present invention relates to a composition containing a particulate solid, a non-polar organic medium, and a compound obtained/obtainable by reacting an aromatic amine with hydrocarbyl-substituted acylating agent, wherein the hydrocarbyl-substituted acylating agent is selected from the group consisting of an oligomer or polymer from condensation polymerization of a hydroxy-substituted C10-30 carboxylic acid into a polyester, an optionally hydroxy-substituted C10-30 carboxylic acid, a C10-30-hydrocarbyl substituted acylating agent, and a polyolefin-substituted maleic anhydride. The invention further provides compositions for inks, thermoplastics, plasticizers, plastisols, crude grinding and flush.

主权项

1. A composition comprising a particulate solid, a non-polar organic medium, and a compound obtained by reacting an aromatic amine with a hydrocarbyl-substituted acylating agent,
wherein the aromatic amine comprises coupling products of 4-aminodiphenylamine represented by the formula (1a): wherein each variable R1 is hydrogen or a C1-5 alkyl group; R2 is hydrogen or a C1-5 alkyl group; U is an aliphatic, alicyclic or aromatic group, and when U is aliphatic, the aliphatic group is a linear or branched alkylene group containing 1 to 2 carbon atoms; and w is 0 to 9, wherein the hydrocarbyl-substituted acylating agent is an oligomer or polymer from condensation polymerisation of a hydroxy-substituted C10-30 carboxylic acid into a polyester, and wherein the particulate solid is a pigment or a filler.
