Disclosed are thickened organic liquid compositions comprising an organic liquid and a polymeric rheology modifier wherein the polymeric rheology modifier is obtainable by co-polymerizing at least two of a bicyclic (meth)acrylate ester, an alkyl (meth)acrylate, and an aromatic vinyl monomer. Also disclosed are thickened organic liquid dispersions with suspended solids and methods of stabilizing dispersions using polymeric rheology modifiers.
