    摘要: Particulate materials useful as fillers, reinforcing agents, radioopacifiers, or impact modifiers. The particulate material has an average particle size range of about 10,000 nm or less and comprises an organic-inorganic hybrid material that has a ceramic material network having organic polymer segments distributed throughout the ceramic network. The ceramic network may be prepared by a sol-gel technique. The particulate material may be compounded in thermoplastic polymer compositions useful in a variety of applications such as preparation of medical device components.
