摘要:
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.

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.

摘要:
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.

摘要:
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.
摘要:
Provided are films made from copolyesters having improved oil repellency as compared to conventional copolyesters. The copolyesters are derived from certain perfluorinated monomers.
摘要:
Disclosed are polyesters, particularly poly(trimethylene terephthalate), comprising fluorovinylether functionalized aromatic repeat units, and methods to make the polyester polymers. The polymers are useful for imparting soil resistance to polyesters, particularly in the form of fibers, fabrics, and carpets.
摘要:
Polyester nanocomposite compositions contain silica nanoparticles that have been subjected to surface treatment with novel trialkoxysilane compositions. The novel silane compositions are prepared by reacting a 3-isocyanatopropyl trialkoxysilane with 1,3-propanediol or certain polyether diols. The silica nanoparticles exhibit improved dispersion in the polyester. This leads to haze reduction and improvements in mechanical properties.
