A composition comprising a particulate solid, an organic or aqueous medium and a polymer comprising at least 1 to 100, or 1 to 50 repeat units, wherein the repeat units have structures (a) and (b) comprising: (a) 5 to 60 mole percent of repeat units represented by: and (b) 40 to 95 mole percent of repeat units represented by: wherein each R 1 is independently a C 1 -C 100 hydrocarbyl group; and each R 2 is represented by R 3 is independently selected from the group consisting of hydrogen, and any C 1 to C 24 hydrocarbyl group; X 1, X 2, X 3, X 4, X 5, and X 6 is independently selected from the group consisting of hydrogen, phenyl, methyl and ethyl, subject to the proviso that at least one of the two X groups that are attached to the same polyoxyalkylene oxyalkylene unit are hydrogen; p, q, and r are each independently any integer between zero and 100, including zero, subject to the proviso that at least one of p, q, and r is not zero; R 4 is independently a C 1-30, or C 6-24, or C 8-18 hydrocarbyl group; and s is either 0 or 1. (a) 5 to 60 mole percent of repeat units represented by: and (b) 40 to 95 mole percent of repeat units represented by: wherein each R 1 is independently a C 1 -C 100 hydrocarbyl group; and each R 2 is represented by R 3 is independently selected from the group consisting of hydrogen, and any C 1 to C 24 hydrocarbyl group; X 1, X 2, X 3, X 4, X 5, and X 6 is independently selected from the group consisting of hydrogen, phenyl, methyl and ethyl, subject to the proviso that at least one of the two X groups that are attached to the same polyoxyalkylene oxyalkylene unit are hydrogen; p, q, and r are each independently any integer between zero and 100, including zero, subject to the proviso that at least one of p, q, and r is not zero; R 4 is independently a C 1-30, or C 6-24, or C 8-18 hydrocarbyl group; and s is either 0 or 1. each R 1 is independently a C 1 -C 100 hydrocarbyl group; and each R 2 is represented by R 3 is independently selected from the group consisting of hydrogen, and any C 1 to C 24 hydrocarbyl group; X 1, X 2, X 3, X 4, X 5, and X 6 is independently selected from the group consisting of hydrogen, phenyl, methyl and ethyl, subject to the proviso that at least one of the two X groups that are attached to the same polyoxyalkylene oxyalkylene unit are hydrogen; p, q, and r are each independently any integer between zero and 100, including zero, subject to the proviso that at least one of p, q, and r is not zero; R 4 is independently a C 1-30, or C 6-24, or C 8-18 hydrocarbyl group; and s is either 0 or 1.
