  • 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: 6924322
    Abstract: An organic aerogel or xerogel formed by a sol-gel reaction using starting materials that exhibit similar reactivity to the most commonly used resorcinol starting material. The new starting materials, including thio-, amine- and nitro-containing molecules and functionalized macrocyclic molecules will produce organic xerogels and aerogels that have improved performance in the areas of detection and sensor technology, as well as water stream remediation. Also, further functionalization of these new organic aerogels or xerogels will yield material that can be extracted with greater facility than current organic aerogels.

  • Patent number: 6902849
    Abstract: The present invention relates to a sulfonated polymer membrane and to a process for the preparation thereof. According to the process, a polymer film is irradiated, and the irradiated polymer film is sulfonated in order to link sulfonic acid groups thereto. According to the invention, the sulfonation is continued until the total concentration of sulfonic acid groups in the membrane is 0.4-3.0 meq/g and they are homogeneously distributed in the membrane material in such a manner that their concentration in the middle of the membrane is at minimum 0.2 meq/g. With the help of the invention, it is possible by a rapid and simple process to prepare membranes the chemical and mechanical properties of which can be regulated by means of the selection of the initial film, by irradiation and by the sulfonation process.

  • Patent number: RE38773
    Abstract: The present invention involves the synthesis of a series of amylose (starch) derivatives with various degrees of substitution and amylose/amylopectin ratios. These chains are chemically crosslinked and then mechanically deformed (stretched) to produce a biodegradable and mechanically superior material. Specifically, the process consists of chemically modifying starch into starch derivatives such as starch ethers, starch esters and starch carbamates. The polymers have a percentage degree of substitution of from about 35% to about 95% (degree of substitution is from about 1.05 to about 2.85) and preferably have a percentage degree of substitution of from about 65% to about 90% (degree of substitution is from about 1.95 to about 2.70). The starch derivatives are crosslinked to obtain crosslinked chains and processed into sheets, films, fibers, threads or other articles as known in the art.
