The present invention relates to the pyrolysis of hydrochlorofluorocarbons to form fluoromonomers such as tetrafluoroethylene, the pyrolysis being carried out in a reaction zone lined with nickel and mechanically supported by a jacket of other corrosion resistant metal, the nickel lining providing an improved yield of valuable reaction products.

Porous microcomposites have been prepared from perfluorinated ion-exchange polymer and metal oxides such as silica using the sol-gel process. Such microcomposites possess high surface area and exhibit extremely high catalytic activity.

A photosensitive element for use as a photopolymer printing plate comprising a support, a layer of a photopolymerizable material on the support, and an infrared ablation layer which is ablatable by infrared radiation and substantially opaque to actinic radiation on the photopolymerizable material. The infrared ablation layer comprises at least one infrared absorbing material, a radiation opaque material, and at least one binder which is substantially incompatible with low molecular weight materi...

Modified lead/bismuth/molybdate catalysts containing vanadium, copper, or gold have been prepared, and are selective to the corresponding furan compound from the gas phase oxidation of an unsaturated acyclic hydrocarbon such as butadiene.

A solid surface material is provided with a thin layer of filled polymer integrally formed with a backing of bubble-filled polymer, without an interface or transition zone in the polymer matrix.

Ethylene, dienes and optionally .alpha.-olefins are copolymerized by selected iron complexes of 2,6-pyridinecarbox-aldehydebis(imines) and 2,6-diacylpyridinebis(imines). The resulting copolymers contain residual olefinic unsaturation from the diene monomers, and some of these copolymers contain cyclic units in the main chain.

The present invention relates to ply-twisted yarn and cut-resistant fabric for use in articles of protective clothing. The fabric is cut resistant and form fitting by virtue of cut-resistant synthetic fibers, inorganic fibers and elastomeric fibers being combined in a particular manner.

A poly(trimethylene-ethylene ether) amide comprises a soft segment from poly(trimethylene-ethylene ether) glycol and a polyamide hard segment, preferably joined by ester linkages. The poly(trimethylene-ethylene ether) ester amides in accordance with the invention are particularly useful as shaped articles. The shaped articles are, preferably, prepared from fibers, fabrics or films.

The present invention relates to charge transport compositions. The invention further relates to electronic devices in which there is at least one active layer comprising such charge transport compositions.

A process for the production of a coating layer from a coating composition curable with high-energy radiation on a substrate, comprising the successive steps: a) providing a substrate to be coated, b) applying a backing foil coated on one side with an uncured or at least only partially cured coating layer of a coating composition curable by means of high-energy radiation, with its coated side on the entire surface or at least one sub-zone of the surface of the substrate, c) irradiating the entir...
