| description | The present invention provides amphipathic graft copolymers comprising a hydrophobic polymer portion combined with at least one hydrophilic polymer portion containing pH independent ionic groups. The amphipathic graft copolymers can be prepared employing a procedure which comprises adding at least two hydrophobic monomers, wherein at least one of the monomers is a graftable monomer, and hydrophilic monomers, including at least one anionic and/or cationic pH independent ionic monomer, or a post reactive non-ionic monomer that can be converted to a pH independent ionic derivative, to a reaction medium and free-radical polymerizing said monomers and recovering the thus prepared amphipathic graft copolymer. Stable, substantially non-aqueous solution composition of said copolymer containing less that 15 percent by weight water are also provided. The present invention is also useful in preparing a substantially non-aqueous concentrate formulation of a non-ionic surfactant and an amphipathic graft copolymer composition in admixture with a water insoluble organic pesticide which concentrate formulation can be easily diluted with water to form non-settling, freeze-thaw stable formulations. The present invention further provides methods for the use of water-diluted agricultural pesticide concentrate formulations of the above non-ionic surfactant concentrate formulations in the kill and control of agricultural pest. |
