| 20080207808 | Novel mechanism for immiscible polymer blend compatibilization - A method of compatibilizing immiscible polymers using the mechanical deformation of quaternary amine treated organoclay particles is described. The mechanism decreases the interstitial energy resulting from immiscible polymer domain interfaces into stored mechanical energy. The polymer domains in the immiscible blend get smaller and the resulting compatibilized microcomposite/nanocomposite blend has superior mechanical properties over non compatibilized blends controls of the same materials. | 08-28-2008 |
| 20080227899 | Novel method for polymer RDP-clay nanocomposites and mechanisms for polymer/polymer blending - The invention is directed towards additives for thermoplastic polymers and blends thereof to which an organoclays has been added to form microtactoids in the thermoplastic. The Organoclays are blends of one or more clays which have been treated with one or more of, resorcinol diphosphate, bis-phenol diphosphate or bis(3-T-Butyl-4 hydroxyphenyl-2,4 Di-T-butylphenyl) resorcinol diphosphate or hydroxyl-derived ethers, esters, and amides where aliphatic fatty acids are added to the molecule at the hydroxyl site. | 09-18-2008 |
| 20080234408 | Novel method for producing an organoclay additive for use in polypropylene - The invention is direct to a method of forming a polyolefin blend. First a diphosphate and clay are blended to form an organoclay. The organoclay is blended with a vectoring polymeric material to form a masterbatch. The masterbatch is blended with a polyolefin such as a polyethylene or a polypropylene. | 09-25-2008 |

| 20090042044 | Novel nanocomposite coating for the reduction of pigment particles loss and UV fade and chemical degradation for decorative & structural products made from concrete and concrete composites - Disclosed is a method of bonding a coating material to concrete The process includes applying a coating material to an inner surface of a mold, applying an aqueous solution of a polymeric material and a clay to the coating material and pouring concrete into the mold. Once the concrete is set, the coated concrete is removed from the mold. | 02-12-2009 |
| 20090176911 | Novel masterbatch thermoplastic delivery system - Clays and organoclays which are treated with resorcinol diphosphate and/or bisphenol diphosphate as general nanoparticle particle dispersants and replacements for quaternary amines. The two compounds are used as self-activating and self-dispersing nanoparticles by localizing themselves on the particle surface in a polymer matrix and acting as a nanoparticle dispersants in general, as well as resulting in exfoliation of clays. The exfoliate clays may be used in polymers in lieu of other organic treatments. When these clays exfoliate poorly in a given thermoplastic, they can be added in high loading rates to polymethylmethacrylate and the PMMA-clay masterbatch added to the plastic where the organoclay performed poorly. The resulting material is a desirable nanocomposite material, with good exfoliation of the organoclay obtained in the final receiving thermoplastic. | 07-09-2009 |
