| 20090245939 | DUAL-USE MICRO ENCAPSULATION COMPOSITION FOR HYDROCARBONS AND DETOXIFICATION OF HIGHLY HAZARDOUS CHEMICALS AND SUBSTANCES - A two-component, water based micro encapsulation composition and method for the cleanup of hydrocarbon spills or contaminates on various surfaces and media. The two-part formulation includes a first solution including water in a predetermined ratio of a water soluble alkaline silicate solution having at least one alkali metal and a predetermined ratio of at least one water soluble surfactant; and a second solution including water, a predetermined ratio of water soluble acid, a predetermined ratio of water dispersible polymer, a predetermined ratio of water soluble hydrotrope, and a predetermined ratio of at least one water soluble flocculating agent. A method of using the two-part formulation includes preparing the two-part formulation, allowing the first solution to contact the hydrocarbon or chemical contaminate; allowing the second solution to contact the first solution and contaminate to form a homogeneous mixture; and removing the homogeneous mixture. | 10-01-2009 |
| 20080211140 | METHOD OF MANUFACTURE OF THREE-DIMENSIONAL OBJECTS FOR ABSORPTION OF HYDROCARBONS AND LOW-POLARITY CHEMICALS - The present invention relates to methods of recovering hydrocarbons or low polarity organic chemicals from hard surfaces, water and water surfaces, in their vapor state and from porous substrates. The hydrocarbons or low-polarity organic chemicals may be included in a spill. More particularly, the invention relates to the absorption of certain hydrocarbons and low-polarity organic chemicals by applying thermoplastic elastomers of a triblock copolymer of the general configuration A-B-A. The preferred A-B-A copolymer of the invention is a low to medium molecular weight hydrogenated polystyrene-poly(isoprene+butadiene)-polystyrene or polystyrene-b-ethylene/ethylene-propylene-b-styrene block copolymer. The method of forming a three-dimensional object from a hydrocarbon or low-polarity organic chemical absorbing substance includes: applying pressure to particles of a polymeric material comprising a styrene-ethylene/ethylene/propylene triblock copolymer containing from approximately 20 to 40 percent styrene, and; heating the particles for a period of time sufficient to form the three-dimensional object. | 09-04-2008 |
