    Abstract: Described herein are compositions and methods for stabilizing the ability of hydrated polyacrylamide co-polymers to modify the physical properties of water solutions under high shear conditions. The compositions generally include a water solution including at least one hydrated polyacrylamide co-polymer; and at least one additive selected from the group consisting of i) a component having the formula of Formula 1, where Formula 1 is R1—O-EOa-POb-EOc—POd—R2, where R1 is hydrogen or any C1 to C18 carbon or carbon chain; O is oxygen, EOa is —(CH2CH2—O)a where a can be from 0-500; POb is —(CH(CH3)CH2—O)b where b can be from 0-70; EOc is —(CH2CH2—O)c where c can be from 0-150; POd is —CH(CH3)CH2—O)d where d is from 0-30; and R2 is hydrogen or any C1 to C18 carbon or carbon chain; ii) a tetra functional block copolymer; iii) a polyvinylpyrrolidone (PVP) homopolymer; and iv) any combination thereof.

    Abstract: A method for increasing the efficacy of a herbicide which comprises applying an aqueous spray liquor of the herbicide in combination with an anionic copolymer CP, where the copolymer CP is made of repeating units of polymerized ethylenically unsaturated monomers M comprising a) 50 to 99.5% by weight, based on the total weight of ethylenically unsaturated monomers M, of at least one monomer Ma selected from the group consisting of primary amides of a monoethylenically unsaturated monocarboxylic acid having 3 to 6 carbon atoms; b) 0 to 50% by weight, based on the total weight of ethylenically unsaturated monomers M, of one or more monomers Mb, where the monomer Mb is either—at least one monomer Mb. 1 selected from the group consisting of monoethylenically unsaturated sulfonic acids and the salts thereof; or—at least one monomer Mb.2 selected from the group consisting of monoethylenically unsaturated monomers bearing at least one quaternary ammonium group; and c) 0 to 15% by weight, based on the total weight of ethylenically unsaturated monomers M, of one or more monoethylenically unsaturated monomers Me having at least one poly-C2-C6-alkyleneoxide moiety which has a terminal OH group or a terminal C1-C6-alkxoy group in addition to the moiety bearing an ethylenically unsaturated double bond; where the total amount of monomers Ma and Mb is at least 85% by weight, based on the total weight of ethylenically unsaturated monomers M, and where the total amount monomers Mb and Mc is from 0.5 to 50% by weight, based on the total weight of ethylenically unsaturated monomers M.
