Abstract
The present disclosure provides a dispersant obtained from the reaction of a styrene maleic anhydride and a polyether monoamine. The dispersant may be combined with a pesticide and water to form an aqueous agricultural composition.
Claims8
A non-aqueous dispersant obtained from the reaction of a styrene maleic anhydride copolymer having a styrene to maleic anhydride molar ratio of between 6.0:1.0 to 8.0:1.0 and a polyether monoamine represented by the formula
- wherein R1 is a hydrocarbyl group, X1, X2, X3, are hydrogen, X4 is methyl, X5, and X6 in each occurrence are independently selected from the group consisting of:
- hydrogen, methyl and ethyl, p is 19, q is 3, and r is any integer between zero and about 100, including zero, and, s is either 0 or 1 and the polyether monoamine has a molar ratio of EO to PO greater than or equal to 58/8 and is water soluble and wherein the dispersant has a total solids content, in percent of less than about 60 and more than about 45.
