Abstract: A method of forming an active control ingredient that controls target living species over an extended period of time commences by providing a clay material that has a structure substantially depleted of platelets (“aplatelet”). The aplatelet clay material is heated with a solid active control agent to a temperature of at least about 10° C. above the melting point of the solid active control agent. The aplatelet clay material then is loaded with the heated solid active control agent.

Abstract: One aspect of the invention is a method of controlling target living species with an active ingredient over an extended period of time. This method sorbs an active ingredient into colloidal clay. Next, a polymer pellet recalcitrant to release of the active ingredient is loaded with the sorbed colloidal clay. Finally, the loaded polymer pellet is formed into a barrier, which is adapted to be placed at a location for controlling a target living species. Another aspect is a barrier for controlling a target living species. The formed barrier contains polymer pellets loaded with colloidal clay sorbed with an active ingredient that controls the target living species. The sorbed clay loaded polymer pellets are recalcitrant to release of the active ingredient.

Abstract: Method for forming a control device for control of one or more of root intrusion or plant growth commences by heating a root-controlling agent to its melting point temperature and heating a nanoclay intercalated with an ammonium ion to a temperature of at least the root-controlling agent melting point temperature. The heated root-controlling agent is loaded with the heated intercalated ammonium ion intercalated nanoclay to form a composite material that is partially exfoliated. The particle size of said composite material is adjusted for blending and further exfoliation. The particle size of the composite material is adjusted with a polymer matrix. The nanoclay in the polymer matrix is exfoliated to an extent that a slow controlled release of the root-controlling agent from the polymer matrix is obtained. Finally, the polymer matrix is formed into a fiber to form the control device.

Abstract: A method to control on a sustained basis insect pests wherein the insect pests are exposed to repellent chemicals lodged in a high tortuosity microporous polymeric material.

Abstract: A method for applying a barrier to structures to prevent the infiltration of pest species (unwanted organisms) uses a (e.g., coating) composition formed from a polyurethane (e.g., film-forming) polymer system and a pellet comprising a pesticide incorporated into a sorbent and dispersed in the polyurethane polymer system. The composition protects the structure by application either to the structure or to a pathway that leads to the structure. Advantageous polymer systems include polyurethanes rich in urea linkages and predominating in aliphatic and alicyclic backbones.

Abstract: One aspect of the present invention is a sprayable composition for coating pipe for protecting it from one or more of root intrusion or root growth when the coated pipe is placed underground. Such sprayable formulation includes a 2,6-dinitroaniline herbicide; a polymer pellet impregnated with a 2,6-dinitroanililne herbicide-sorbed colloidal clay; and a film-forming polymer. Another aspect is pipe coated with the dried residue of a coating of a 2,6-dinitroaniline herbicide; a polymer pellet impregnated with a 2,6-dinitroaniline herbicide-sorbed colloidal clay; and a film-forming polymer, wherein the coated pipe is protected from one or more of root intrusion or root growth when the coated pipe is placed underground.

Abstract: This invention provides repellent devices and methods for control of root intrusion and plant growth. One aspect of this invention is a geotextile in which 2,6-dinitroaniline is stored inside the individual filaments. The 2,6-dinitroaniline is stored in nanoclay or smectite clay reservoirs that control the rate of release of the 2,6-dinitroaniline. These reservoir particles are placed in the fibers during the melt spinning production of the fibers or by film-to-fiber processes. The particles are very thin and are oriented within the fibers during the spinning process. These clay reservoirs are superior to conventional carbon-based reservoirs, because the dispersed clay materials have a uniform, e.g., 1-nanometer, thickness that is needed to fit into individual filaments. Nonwoven, woven, or knitting processes are used to make the geotextile fabrics. The fibers of this invention prevent root intrusion into these fabrics.

Abstract: A method for creating an wood destroying organism resistant coating is disclosed. The method involves spraying a structure with a mixture of a quick setting liquid monomer and a pesticide. The monomer, when cured, forms a bonded polyurethane coating upon the surface a structure which slowly releases pesticide over long periods of time. The method may be practiced as a two part system utilizing monomers and catalytic curing agents, and a one part system utilizing masked isocyanates.

Abstract: Disclosed are degradable materials including molded products, laminates, foams, nonwoven materials, adhesives, coatings and films, and particularly packaging films. The materials are made using polydioxaneone polymers comprising at least two different dioxaneone-based repeating units. Preferred polymers are polydioxanediones. First repeating units have less carbon atoms in constituent groups extending from the polymer backbone than second repeating units. Physical characteristics and degradation of the materials can be varied by varying the choice and/or relative proportions of first and second repeating units in the polydioxaneone polymers. Methods for preparing polydioxaneone polymers that can be used in the manufacture of the materials are also discussed, as are suitable monomers and methods for preparing such monomers.
