Abstract: Process for polymerizing by ring opening polymerization of a norbornene-type monomer, or a mixture thereof, with or without at least one other polymerizable monomer, in presence of an alkylaluminum halide cocatalyst and an organoammonium molybdate or tungstate catalyst that is soluble in a hydrocarbon reaction solvent and the norbornene-type monomer.

Abstract: An alkane is reacted with oxygen and available chlorine in the presence of a solid solution catalyst containing iron cations to yield unsaturated hydrocarbons and chlorinated saturated and unsaturated hydrocarbons. In a preferred embodiment of the process, ethane is reacted with oxygen and available chlorine in the presence of a solid solution catalyst containing iron cations to yield vinyl chloride, ethylene, and other valuable by-products. The conversion of ethane to products approaches 100 percent, vinyl chloride is prepared in up to 40 mole percent yield, and the combined yield of vinyl chloride, ethylene dichloride, ethyl chloride, and ethylene is up to 90 mole percent.

Abstract: Polymer compositions are disclosed that contain finely-divided additives of sulfate glasses and sulfate glass-ceramic materials comprised of potassium sulfate and zinc sulfate as smoke retardant additives. Glass sulfates and glass-ceramic materials comprised of potassium sulfate, zinc sulfate and sodium sulfate produce results superior to those obtained using the potassium sulfate-zinc sulfate binary system. The inclusion of a transition metal sulfate as a component of the sulfate glass or sulfate glass-ceramic material also produces superior results over those resulting from use of the potassium sulfate-zinc sulfate binary glasses and glass-ceramic materials.

Abstract: Amine molybdates are formed by reacting molybdenum trioxide (MoO.sub.3) with an amine in an aqueous medium essentially free of acid and in which is dissolved a water-soluble ammonium or monovalent metal or divalent metal or trivalent rare earth metal salt of an acid, or a combination thereof. Although the reaction may be carried out at room temperature, the reaction mixture desirably is heated to between about 75.degree. C. to 110.degree. C. and preferably is refluxed to reduce the time required for completion of the reaction. The reaction slurry is stirred while the reaction is occurring. Upon completion of the reaction, the amine molybdate is separated from the liquid phase, and is washed and dried. After removal of the solid amine molybdate from the slurry the liquid component can be reused avoiding possible environmental difficulties.
