| 523132000 | Composition for in situ soil conditioning or treating or process of preparing | 6 |
| 20080214696 | COMPOSITIONS AND METHODS FOR RESISTING SOIL EROSION & FIRE RETARDATION - Compositions and methods for concomitantly resisting fire and soil erosion. The compositions comprise an aqueous mixture of a polymer mixed with an organic material. The polymer preferably comprises polyacrylamide or a copolymer of polyacrylamide having anionic functional groups. The organic material comprises either cellulose, mulch and/or seed and mulch. The methods of the present invention comprise providing or forming an aqueous mixture of the compositions of the present invention and applying them to an area of land sought to be provided with soil erosion and/or fire resistant properties. | 09-04-2008 |
| 20090239973 | Polyacrylamide Delivery Product - The PAM delivery product is a solid form of polyacrylamide polymer (PAM). Among other things, the PAM delivery product can be used to prevent ruts formed during center-pivot irrigation, prevent erosion of irrigation ditches, clarify wastewater, and assist seed germination and seedling establishment. The PAM delivery product includes pure PAM and water to create a solid “loaf.” Water-soluble calcium (Ca) can also be added to the PAM delivery product depending on the specific application for the PAM delivery product. When Ca is used in the PAM delivery product, it is present in a 9:1 ratio to the PAM There are no fixing agents needed in the PAM delivery product; it is pure active ingredient. | 09-24-2009 |
| 20100125111 | COMPOSITIONS AND METHODS FOR RESISTING SOIL EROSION AND FIRE RETARDATION - Compositions and methods for resisting soil erosion. The compositions comprise a polymer mixed with an organic material. The polymer preferably comprises polyacrylamide or an acrylamide copolymer having anionic functional groups. A second polymer to promote the formation of a film may also be utilized. The organic material comprises natural and synthetic fiber material. The methods of the present invention comprises applying the compositions of the present invention to an area of land sought to be provided with soil erosion resistant properties and thereafter allowing water to mix therewith, as may be supplied or provided naturally by precipitation. | 05-20-2010 |
| 20130197128 | METHOD AND COMPOSITION FOR ROAD CONSTRUCTION AND SURFACING - Methods and compositions for improving the strength and longevity of secondary roadways through environmentally sound practices are disclosed herein. A composition for road sealing includes an aqueous emulsion of acrylic and vinyl acetate polymer, water, and a resin-modified emulsion, wherein the resin-modified emulsion includes a mixture of pitch and rosin, an emulsifying agent, and water. | 08-01-2013 |
| 20140323609 | POLYACRYLAMIDE BASED AGRICULTURAL COMPOSITIONS - A polyacrylamide based agricultural composition as a microemulsion is provided in form of a water-in-oil microemulsion with polyacrylamide dissolved in the water phase where the polyacrylamide solids content is from about two up to about 15 percent by weight, which is then further diluted in water at the time of use to impart the desired characteristics of the polymer to the water phase or to the material to which the water phase is applied. | 10-30-2014 |
| 20150031786 | Process for Producing a Powder Comprising an Extruded Carrier With an Active Compound - This invention provides processes for forming powders comprising at least one active compound and at least one carrier. The processes comprise (i) heating at least one active compound to at least its melting point or softening point; and (ii) in an extruder, combining at least the at least one active compound with at least one carrier, to form combined ingredients, and cooling the combined ingredients as they pass through the extruder, such that the combined ingredients exit the extruder at about ambient temperature in the form of a powder having particles sized so that about 95 wt % or more of the powder passes through a screen of about 8 standard U.S. mesh. | 01-29-2015 |
