The present invention relates to methods of using an aqueous composition or dispersion containing a water-soluble or water-dispersible synthetic polymer, and compositions formed thereof. The aqueous composition or dispersion is added to agricultural spray compositions, ink compositions, deicing or anti-icing compositions, latex paint and coating compositions, cleaner compositions, adhesives, fire-extinguishing chemical compositions, hydro-metallurgy/electro-winning compositions, compositions having organosilanes, personal care compositions, water-based hydraulic compositions, dust control compositions, and textile finish compositions, to impart properties including aerosol control, spatter control, shear stability, rheology control, transfer efficiency, oil/water reduction, sling control, emollient performance, film forming capability, surface activity, encapsulent ability, lubricity, thickening, and anti-wear capability, to the resultant composition formed thereof.

1. A method of imparting aerosol control and shear stability to a first composition comprising incorporating therein an aqueous composition or dispersion comprising about 1 to about 5000 parts per million of a water-soluble or water-dispersible synthetic polymer formed by polymerizing(A) a hydrophobic monomer selected from the group consisting of A(I) an alkyl substituted acrylamide compound having the formula: [EQU12] wherein R1 is a hydrogen or a methyl group and R2 and R3 are independently hydrogen or hydrocarbyl groups, provided that the total number of carbon atoms in R2 and R3 combined is between 4 and 36, and A(II) an acrylate ester of the following formula: [EQU13] where R1 is a hydrogen or a methyl group and R9 is a hydrocarbyl group containing between 1 and 20 carbon atoms; and (B) a hydrophilic monomer selected from the group consisting of B(I) acrylamido sulfonic acids having the formula: [EQU14] wherein R4 is a hydrogen or a methyl group and R is an aliphatic or aromatic hydrocarbon group containing from 2 to 12 carbon atoms; B(II) acrylamido disulfonic acids having the formula: [EQU15] wherein R4 is a hydrogen or a methyl group and R is an aliphatic or aromatic hydrocarbon group containing from 2 to 8 carbon atoms, and B(III) a styrene sulfonic acid having the formula: [EQU16] wherein R4 is a H or a methyl group, and X+ is H or a cation selected from the group consisting of alkali metal cations, alkaline earth cations, cations of the transition metals: Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, and ammonium cations of the following formula: R5R6R7R8N+ wherein R5, R6R7, and R8 are independently hydrogen or hydrocarbyl groups, provided that the total number of carbon atoms in an ammonium cation does not exceed 21 carbon atoms, and further provided that if A is A(I), then the ratio of moles of A to B is from about 95:5 to about 1:99, and if A is A(II), then the ratio of moles of A to B is from about 75:25 to about 1:99, whereby said first composition retains effective aerosol control properties even after it is subjected to a shear rate of from about 99,000 to about 1,000,000 s-1, and a shear stress of from about 30,000 pascals to about 500,000 pascals.
