Patent number: 8545691Abstract: A super absorbent polymer material is contacted with an aqueous medium to absorb at least a portion of the aqueous medium. At least portion of the aqueous medium absorbed super absorbent material is subsequently regenerated to release water therefrom and to form a regenerated super absorbent material suitable for the contacting with a second quantity of an aqueous medium. Also disclosed are layered composites including an electrically conductive metal support layer, a layer of super absorbent material disposed thereon, and a layer of a selective semi-permeable material disposed adjacent the layer of the super absorbent material and spaced apart from the electrically conductive metal support layer.Type: GrantFiled: April 30, 2009Date of Patent: October 1, 2013Assignee: Illinois Institute of TechnologyInventors: Fouad Teymour, Said Al-Hallaj

Patent number: 8013036Abstract: Modified scrap rubber particles, a method for forming the modified rubber particles and compositions including the modified rubber particles. The rubber particles are impregnated with at least one polymerizable monomer and polymerized to impregnate the rubber particles with a polymer. The impregnated polymer provides the modified rubber particles with improved properties which increase the potential uses for recycled scrap rubber. The modified rubber particles are useful in surface coatings, such as latex paint or powder coatings and can be used as a soil substitute.Type: GrantFiled: February 24, 2010Date of Patent: September 6, 2011Assignee: Illinois Institute of TechnologyInventors: Nima Shahidi, Hamid Arastoopour, Fouad Teymour

Publication number: 20040048987Abstract: A method is provided for producing hyperbranched polymers comprising heating a polymerizable reaction charge comprising (a) a monomer mixture comprising 50-99.1% by weight of at least one monoethylenically unsaturated monomer and 0.1-50% by weight of one or more multiethylenically unsaturated monomers and (b) if at least one ethylenically unsaturated monomer of the monomer mixture is not a thermally initiating monomer, a free radical polymerization initiator, to a temperature in the range from about 250° C. to about 400° C. in a continuous reactor which allows mixing of the reactor contents for a residence time of from about 2 minutes to about 60 minutes, provided that if the total amount of multiethylenically unsaturated monomer is less than 3% by weight of the monomer mixture than at least one of said one or more multiethylenically unsaturated monomers must be tri- or greater ethylenically unsaturated.

Patent number: 6689853Abstract: The present invention provides a high temperature continuous polymerization and condensation process for preparing a polymeric product. The process includes continuously charging into a reaction zone: at least one radically-polymerizable monomer having a radically polymerizable group and at least one condensation reactive functionality; and at least one modifying agent having a functional group capable of reacting with the condensation reactive functionality. The reaction zone includes at least one primary reactor, but may, and preferably does, contain a secondary reactor. The process further includes maintaining an effective temperature in the primary reactor to cause polymerization of the monomer and to allow at least a portion of the condensation reactive functionality to react with the functional group of the modifying agent.Type: GrantFiled: December 6, 2001Date of Patent: February 10, 2004Assignee: Johnson Polymer, LLCInventors: John D. Campbell, Jon A. Debling, Douglas J. DeYoung, Ioannis Giannakitsas, Dean R. Hellwig, David D. Schatz, Fouad Teymour, Marco A. Villalobos

Patent number: 6388026Abstract: A process for preparing low molecular weight homomacromers and comacromers which includes (a) charging a reactor with (i) ethylenically unsaturated monomers selected from the group consisting of acrylic monomers or monoalkenyl aromatic monomers and (ii) if said ethylenically unsaturated monomer is not a thermally initiating monomer, a free radical polymerizable initiator, to form a polymerizable reaction charge. The reaction charge is heated during continuous mixing in the reactor to reaction temperature in the range from about 180° C. to about 500° C. for a residence time greater than 5 minutes to form the low molecular weight homomacromers or comacromers. If the residence time is 60 minutes or less, the reaction temperature is greater than 270° C. and if the reaction charge is a mixture of acrylic monomer and monoalkenyl monomer and the residence time is 60 minutes or less then the reaction temperature is greater than 310° C.Type: GrantFiled: August 5, 1997Date of Patent: May 14, 2002Assignee: S.
