Abstract: Fluorinated ethers of aromatic acids are produced from halogenated aromatic acids in a reaction mixture containing a copper (I) or copper (II) source and an amino acid ligand that coordinates to copper. The fluorinated ethers of aromatic acids made using the process described herein can be applied to, e.g., fibers, yarns, carpets, garments, films, molded parts, paper and cardboard, stone, and tile to impart soil, water and oil resistance. By incorporating the fluorinated ethers of aromatic acids, or diesters thereof, into polymer backbones, more lasting soil, water and oil resistance, as well as improved flame retardance, can be achieved.

Abstract: Dimensionally stable, shaped articles comprised of dried, aggregated, water-swellable hydrogel microspheres are described. The microspheres are aggregated together without the use of a binding agent. When exposed to an aqueous medium in a container, the dimensionally stable, shaped article swells slowly and disaggregates, forming at least partially swollen hydrogel microspheres, which take the shape of the container. The dimensionally stable, shaped articles disclosed herein have many potential applications, including medical applications such as a medical implant.

Abstract: A method for making polyester nanocomposite materials by polymerization in the presence of exfoliated fibrous clay nanoparticles includes dispersing the nanoparticles in a mixture of diol, water, and sodium salt before polymerization, thereby improving the dispersion of the nanoparticles in the final nanocomposite. This results in enhanced mechanical properties, such as modulus, in articles made from the nanocomposite.

Abstract: A process for producing microspheres was developed that provides microspheres with new combined properties of high density, low fracture, high swell capacity, rapid swell, and deformability following swell. The process is reliable and high yielding, and makes use of a low temperature azo initiator and a small molecule chlorinated solvent as the organic phase. The microsphere preparation made using the process is particularly useful in medical treatments such as embolization.

Abstract: Using chelated organic titanate catalysts in the preparation of polyester/sepiolite-type clay nanocomposites by in situ polymerization results in a polymer whose moldings exhibit higher tensile modulus than when open-site organic titanate catalysts are used.

Abstract: A method for making poly(ether-ester) and poly(butylene terephthalate) nanocomposite materials by polymerization in the presence of exfoliated fibrous clay nanoparticles includes dispersing the nanoparticles in a mixture of diol and water before polymerization, thereby improving the dispersion of the nanoparticles in the final nanocomposite.

Abstract: A method for embolization treatment was developed in which microspheres with novel properties are administered in a mammal. The microspheres are made using a novel process that results in microspheres with new combined properties of high density, low fracture, high swell capacity, rapid swell, and deformability following swell. These microspheres form occlusions with high durability, withstanding over 100 mm Hg (13.3 kPa) of pressure.

Abstract: A method for medical treatment was developed in which microspheres with novel properties are administered in a mammal. The microspheres are made using a novel process that results in microspheres with new combined properties of high density, low fracture, high swell capacity, rapid swell, and deformability following swell. These microspheres may be administered for void filling, tissue bulking, non-vasculature occlusion, body fluid absorption, and delivery of medications.
