C-7530 THERMOPLASTIC POLYMER PRIMARILY PLASTICIZED WITH HERBICIDE OF THE PRESENT INVENTION The present invention relates to compositions formed by mixing herbicides with polymers. The herbicide acts, as a primary plasticizer, to plasticize the resin and exudes from the resin/herbicide composition over a period of time. The polymer/herbicide composition can be in the form of an aqueous latex, suitable for coating of a substrate, can be in the form of a plasticized resin capable of being formed into articles of manufacture (e.g., lawn edging), or can be in the form of an extrudable plasticized latex which can be directly applied to the soil locus (e.g. to a trench) and allowed to stand. Control over the amount and type of surfactant used in the manufacture of the polymer with which the herbicide is to be mixed can influence the rate and amount of herbicide that exudes from the composition. * * * * * * * |
