    摘要： The present invention relates to novel compositions of matter comprising fullerenes and polymers, wherein the fullerenes are combined with the polymer in an amount sufficient to result in a change or modification in the viscoelastic properties of the resulting composition from that of the unmodified polymer typically within the range of from about 0.01 wt. % to about 85 wt. %. Also included in the present invention is the process for making the novel fullerene-polymer compositions and the products produced by the process disclosed therein. The novel compositions show changes in the viscoelastic properties in comparison to the unmodified polymer, and hence, have utility in any application in which the unmodified polymer may be used, but wherein the application would benefit from the resulting change in the viscoelastic properties.

    摘要： Epoxy interpenetrating polymer networks having chemical bonds between the interpenetrating networks are prepared from a first and a second polymer network, at least one of which contains an EPRXE resin; a resin having two epoxide functionalities represented by E and a reactive pendant nonepoxide functionality X. The two resin networks are sequentially crosslinked followed by activation of the pendant functionality of the EPRXE resin to form internetwork chemical bonds between the two resin networks affording an epoxy resin with both increased strength and toughness. The invention is also directed to the process of making interpenetrating polymer networks.

    摘要： The present invention relates to a novel process for producing silicon and/or aluminum containing iron alloy product as well as the material produced from same in either sheet or bulk structure form for electromagnetic circuit application. The process entails modifying an iron feedstock containing less than about 2.5 wt % silicon, aluminum or a combination thereof. The process further consists of diffusion of silicon or silicon and aluminum or aluminum into an iron feedstock by a pack diffusion or a chemical vapor deposition method in which the iron feedstock is heated to a temperature at which diffusion occurs in the presence of a pack containing silicon and/or aluminum sources, a reducing agent, a catalyst, and a filler, or in the presence of a flowing gas stream containing a volatile silicon compound. The resulting iron alloy product, which has a silicon content in the range of 0.25%--7% silicon, and an aluminum content in the range of about 0%--4% aluminum, has favorable properties for motor and transformer applications.
