Abstract: Catalysts and processes for the catalytic conversion of hydrocarbons to carbon monoxide and hydrogen employing new families of chromium-rare earth based catalysts are disclosed. One highly active and selective catalyst system, providing greater than 95% CH4 conversion, and 97-98% selectivity to CO and H2 by a net catalytic partial oxidation reaction, is a Ce—Cr—Ni containing compound. A preferred process for the catalytic conversion of a hydrocarbon comprises contacting a feed stream comprising a methane-containing hydrocarbon feedstock and an oxygen-containing gas with a chromium-rare earth containing catalyst in a short contact time reactor maintained at partial oxidation promoting conditions effective to produce synthesis gas.

Abstract: Stable, concentrated solutions of high molecular weight polyaniline. In order to process high quality fibers and other articles possessing good mechanical properties, it is known that solution concentrations of the chosen polymer should be in the range from 15-30% (w/w). Moreover, it is desirable to use the highest molecular weight consistent with the solubility properties of the polymer. However, such solutions are inherently unstable, forming gels before processing can be achieved. The present invention describes the addition gel inhibitors (GIs) to the polymer solution, thereby permitting high concentrations (>15% (w/w)) of high molecular weight ((M.sub.w)>120,000, and (M.sub.n)>30,000) emeraldine base (EB) polyaniline to be dissolved. Secondary amines have been used for this purpose in concentrations which are small compared to those which might otherwise be used in a cosolvent role therefor.

Abstract: Disclosed herein are processes for polymerizing ethylene, acyclic olefins, and/or selected cyclic olefins, and optionally selected olefinic esters or carboxylic acids, and other monomers. The polymerizations are catalyzed by selected transition metal compounds, and sometimes other co-catalysts. Sine some of the polymerizations exhibit some characteristics of living polymerizations, block copolymers can be readily made. Many of the polymers produced are often novel, particularly in regard to their microstructure, which gives some of them unusual properties. Numerous novel catalysts are disclosed, as well as some novel processes for making them. The polymers made are useful as elastomers, molding resins, in adhesives, etc. Also described herein is the synthesis of linear .alpha.-olefins by the oligomerization of ethylene using as a catalyst system a combination a nickel compound having a selected .alpha.-diimine ligand and a selected Lewis or Bronsted acid, or by contacting selected .alpha.

Abstract: An absorbent material comprising a mixture of (1) a plurality of absorbent gelling particles comprising a water-insoluble, water-swellable polymer, and (2) an absorbent property modification polymer reactive with at least one component included in a urine. The mixture is made by (i) applying a solution containing an organic solvent, water and the absorbent property modification polymer onto the plurality of absorbent gelling particles, wherein the weight ratio of the organic solvent to the water is at least 50:50, and (ii) removing a portion of the organic solvent and water from the applied absorbent gelling particles. When a urine is applied to the absorbent material, the absorbent gelling particles are spontaneously connective through the absorbent property modification polymer. The absorbent material has at least one of the improved absorbent properties after swelling such as (1) liquid permeability, (2) porosity, (3) wet integrity, and (4) recovery property when subjected to external forces.
