Abstract: A process is disclosed for preparation of telechelic difunctional unsaturated oligomers and polymers having at least one internal carbon-to-carbon double bond wherein the functional groups are terminal reactive groups. The reactants are acyclic polyenes with terminal carbon-to-carbon double bonds and olefins with at least one functional group. The polymerization process is substantially free of side reactions comprising double bond migration and cyclization. The telechelic difunctional unsaturated oligomers and polymers have a functionality of about 2 and are suitable for preparation of block copolymers, ion exchange resins, adhesives, and flocculants and for further functionalization.

Abstract: A method for halogenating hydrocarbons wherein a reaction mixture including a hydrocarbon-containing feed, a hydrogen halide and an oxygen-containing gas is contacted at appropriate reaction conditions with a catalyst of copper aluminum borate to form halogenated hydrocarbons.

Abstract: A process for the halogen-assisted conversion of lower alkanes to higher molecular weight hydrocarbons is provided. A first reaction mixture including lower alkanes, a hydrogen halide and an oxygen-containing gas are contacted with a catalytic composition of crystalline copper aluminum borate at appropriate reaction conditions to form an intermediate composition including halogenated alkanes. The halogenated alkanes are subsequently contacted with a catalytic composition of a pentasil molecular sieve material under appropriate reaction conditions to form a product mixture including hydrocarbons having molecular weights greater than the lower alkanes.

Abstract: A method for converting halocarbons, especially lower halocarbons like chloromethane, especially methyl chloride, to hydrocarbons, especially higher molecular weight hydrocarbons, wherein a reaction mixture including the halocarbons is contacted with a borosilicate-containing catalytic composition having a specified composition in terms of mole ratios of oxides and a specified X-ray diffraction pattern to form a product mixture of the desired hydrocarbon(s).

Abstract: A process for the catalyzed oligomerization of ethylene to a product rich in linear C.sub.4 olefins using a catalyst composition made by incorporating a major amount of HAMS-1B crystalline borosilicate molecular sieve composited in an inorganic matrix or an amorphous, silica-alumina support with minor amounts of a nickel compound and a zinc compound and calcining the result to form a composite containing supported zinc and nickel oxides.

Abstract: Regioselective and stereoselective synthesis of trans-internal olefins is effected with transition metal catalyst complexes having pairs of associated active sites. Photolytic conditions are generally employed.
