    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: 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.
