  • Patent number: 7105587
    Abstract: A method and composition for polymer-reinforced composite cementitious construction materials is described. In one embodiment, a crosslinking component is mixed with a high molecular weight strengthening component and an inorganic cementitious material. The addition of the mixture to water causes a crosslinked molecular network to form within the hydrated, composite cementitious construction material. Both enhanced flexural strength and improved nail-pull resistance are shown, allowing a reduction in weight of the composite cementitious construction material compared to cementitious construction materials made according to other known methods.

  • Patent number: 7101426
    Abstract: An in situ ionic interaction between two additives, one a cationic strength enhancing additive and one an anionic crosslinking additive, is used to improve the mechanical properties of an article formed from a composite material. The composite has a discrete phase bound together with a film of the additives, such as gypsum crystals bound together by a film of substituted starch or cellulose ether.

  • Patent number: 7048794
    Abstract: An inorganic-organic composite comprises an inorganic phase, such as gypsum crystals, and a film forming organic phase. The film forming organic phase is selected from substituted starches having a degree of polymerization; degree of substitution and viscosity such that the substituted starches are insoluble in water during mixing but dissolve at a higher processing temperature during forming, setting or drying of the composite. Thus, excessive migration of the substitute starch is prevented and the composite is substantially strengthened.

  • Patent number: 7037990
    Abstract: A method is provided for the polymerization of olefins substituted with a functional group using a transition metal catalyst that, by virtue of one or more stabilizing groups incorporated within the catalyst structure, “fixes” the stereoconfiguration of each olefinic monomer relative to the transition metal complex during each successive reaction in the polymerization process. The invention substantially reduces the likelihood of olefin rearrangement at the active site of the catalyst during polymerization. In one particular embodiment, the functional group is a polar, electron-donating group and the stabilizing group is a Lewis acid substituent; examples of polymers that can be prepared with such a system include poly(vinyl acetate), poly(vinyl alcohol), and poly(vinyl ethers). Novel complexes and catalyst systems useful in the polymerization method are also provided.

  • Patent number: 7033840
    Abstract: Workstation, apparatuses and methods for the high-throughput synthesis, screening and/or characterization of combinatorial libraries. The invention relates to an array, which permits various high-throughput methods for synthesis, screening and/or characterization in the same array, without requiring sample transfer from the array. In a preferred embodiment, the synthesis, screening, and/or characterization steps are carried out in a highly parallel fashion, where more than one compound is synthesized, screened, and/or characterized at the same time. The invention may be practiced at the microscale. The array may comprise thermal channels, for regulating the temperature of the wells in the array. The wells of the array may comprise a membrane, which is used in various screening and characterization methods. The invention also relates to a covered array, comprising the array and an array cover, as well as an apparatus comprising the array, which comprises the array, an array cover and a stage.

  • Patent number: 6955844
    Abstract: Construction materials containing surface modified reinforcements are used to fabricate composite structures. The composite structures comprise a matrix material and surface modified reinforcements, such as fibers and particulates. The surface modifier may be applied to a fiber surface using conventional sizing equipment and provides a durable film on the fiber. The surface modifier may be selected to have multifunctional properties, for example, increasing fiber pull-out strength, imparting bio-active properties, improving moisture resistance and other desirable properties to the composite structure.

  • Patent number: 6902797
    Abstract: A gypsum-based composite structure is prepared from a slurry comprising a mixture of calcium sulfate hemihydrate, a cellulose ether additive other than CMC and an amount of water that is sufficient to form a slurry. The calcium sulfate hemihydrate is hydrated by the water forming a wallboard core reinforced by the cellulose ether additive. The concentration, viscosity grade and degree of substitution of the cellulose ether are selected to give the composite improved nail pull resistance and greater flexural strength.

  • Patent number: 6872241
    Abstract: The present invention provides an anti-pathogenic air filtration medium comprising a fibrous substrate whose fibers are coated with coating comprising a polymer. The coating provides an environment that is destructive to airborne pathogens. In particular, the filter medium can be used in a building air handling system that both filters the air and eliminates pathogens. The filter medium also can be used to create a new bio-protective gas mask that not only offers protection against chemical warfare agents, but also provides protection against biological pathogens.

  • Patent number: 6841232
    Abstract: A reinforced wallboard core is prepared from a slurry comprising a mixture of ?-calcium sulfate hemihydrate, a cellulose ether additive other than CMC and an amount of water that is sufficient to form a slurry and resulting in a wallboard density of less than 0.8 g/cc. The ?-calcium sulfate hemihydrate is hydrated by the water forming a wallboard core reinforced by the cellulose ether additive. The cellulose ether, having a molecular weight of at least about 20,000 and a viscosity grade of at least about 100 cps, is selected to give the reinforced wallboard core improved nail pull resistance and greater flexural strength than unreinforced wallboard of the same density. The reinforced wallboard core may be used for reduced-paper wallboard and/or for lightweight wallboard, for example.

  • Patent number: 6743830
    Abstract: The present invention discloses a composition of matter for use in wallboard in the construction that has a morphology of pores and a network of interconnected inorganic particles that are coated with a thin layer of organic binder. The process used to produce the wallboard can use either hydrophobic or hydrophilic prepolymers or preferably both to create the desired network of coated inorganic particles. A preferred embodiment uses at least one hydrophobic constituent and a decomposition reaction that produces a gas to form one or more layers or a gradient of the morphology in one or more layers to create wallboard products with superior properties to those wallboard products now known.
