Abstract
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.
Claims10
A compound obtained by reacting an aromatic amine with a hydrocarbyl-substituted acylating agent, wherein the hydrocarbyl-substituted acylating agent is selected from the group consisting of a C10-30-hydrocarbyl substituted acylating agent, an oligomer or polymer from condensation polymerisation of a hydroxy-substituted C10-30 carboxylic acid into a polyester, and an optionally hydroxy-substituted C10-30 carboxylic acid, or mixtures thereof, wherein the aromatic amine is represented by the Formula (1a):
- wherein independently 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, with the proviso that when U is aliphatic, the aliphatic group may be linear or branched alkylene group containing 1 to 5 carbon atoms;
- and
- w is 1 to 10.
