Abstract: A process is provided for preparing a N-halothiosulfonamide modified polyolefin of at least one 1-alkene, and at least one diene which, after incorporation in the polyolefin includes a carbon atom which is fully substituted, for example, 5-ethylidene-2-norbornene. The process comprises reacting a N-halothiosulfonamide with the polyolefin in the presence of a non-nucleophilic base and a catalyst comprising a salt of a weak acid of specified metals. The process is particularly suited to be performed in the melt phase.

Abstract: A method for removing a tertiary halide from an olefin hydrocarbon stream which comprises contacting the hydrocarbon stream with activated alumina at a temperature of about -40.degree. to about 120.degree. C.

Abstract: N-halothiosulfonamide-modified non-rubbery thermoplastic polyolefins are provided. The modified polyolefin products are prepared by reaction of a non-rubbery thermoplastic polyolefin polymer with an N-halothiosulfonamide in the absence or, preferably, in the presence of a catalyst. The preferred catalyst for use in the preparation of these products are salts of weak acids of specified metals.

Abstract: N-halothiosulfonamide-modified rubber products are provided. The modified rubber products are prepared by reaction of a rubber, such as a butyl rubber or a halogenated butyl rubber, with a N-halothiosulfonamide in the absence or in the presence of a catalyst.

Abstract: This invention relates to bidentate transition metal catalyst compositions useful for coordination polymerization of alpha olefin monomers. The novel catalyst compounds are prepared by:(1) reacting a transition trihalide, a transition metal trialkoxide or mixed tri(halide/alkoxide), or the adducts of these materials with Lewis bases, with two equivalents of a bidentate chelating ligand; or(2) reacting two equivalents of the same or different transition metal (+3) tris chelates with one equivalent of a transition metal trihalide or its adduct with Lewis bases.The invention chelating ligands are those which contain at least two, and preferably not more than two, hetero atoms such as O, N, P, or S, separated by a hydrocarbon radical providing sufficient chain length so as to allow both hetero atoms to chelate the same metal atom. The chelating ligand must have at least one easily removable positive ion which is lost on chelation to afford a uninegative, bidentate ligand.

Abstract: Thermoplastic compositions are prepared by blending an ethylene-hexene and/or an ethylene-butene copolymer resin, with a rubber and dynamically vulcanizing the rubber to form a heat-shrinkable dynamically vulcanized alloy of exceptionally low hardness, and great flexibility and elasticity. The preferred rubber is halogenated butyl rubber. Uncured rubber can be included in the composition.

Abstract: Preparation of halothio-sulfonamide-modified terpolymers having a low degree of unsaturation is accomplished by preferably reacting N-chlorothio-sulfonamide with an ethylene-(alpha-olefin)-diene monomer terpolymer comprising, for example, 1,4- hexadiene and/or dicyclopentadiene, in the presence of a catalyst of the formula MAn, where A is an anion or mixture of anions of a weak acid, and M is a metal selected from copper, antimony, bismuth and tin and n is a number which corresponds to the oxidation state of M divided by the valence of said weak acid anion. The reaction is preferably carried out in a melt phase process. Additionally, metals such as zinc and iron can be used at low concentrations in a melt phase process or at short reaction times in a solution process. Mixtures of such modified terpolymers with highly unsaturated rubbery polymers and vulcanizates of such mixtures are particularly useful in pneumatic tire sidewalls.

Abstract: Unsaturated light hydrocarbons are produced by coking a heavy hydrocarbonaceous oil in a conventional fluid coking zone and subsequently heating the vaporous coker product to a higher temperature in a gas-solids separation zone, such as the coking reactor's cyclone separator, with hot solids derived from a coke gasification zone.

Abstract: A low sulfur coke product is obtained in an integrated fluid coking and gasification process in which an oxygen-containing gas is introduced into the upper portion of the gasification zone and steam is introduced into the lower portion of the gasification zone. The desired degree of coke desulfurization is controlled by controlling the thickness of the gasifier coke layer on the gaseous reactor leaving solids per pass.

Abstract: A hydrodesulfurization process is conducted in the presence of an added C1 to C4 alcohol, preferably methanol, or an alcohol-water mixture. The addition of alcohol improves the activity of the catalyst and results in a net production of heat which can be utilized to vaporize the incoming alcohol.

Abstract: A catalytic cracking of hydrocarbons in the presence of an added olefin-containing naphtha increases the selectivity and yield of middle distillate.

Abstract: A hydrocarbon feed is isomerized in liquid phase in the presence of a metal halide catalyst, a hydrogen halide solvent and hydrogen at a temperature ranging from at least 50.degree.C and not greater than the critical temperature of the mixture of the hydrocarbon feed and the hydrogen halide. The partial pressure of the hydrocarbon feed-hydrogen halide mixture is maintained to be at least equal to the critical pressure of the hydrocarbon feed and not greater than the critical pressure of the mixture of the hydrocarbon feed and the hydrogen halide. The molar ratio of the hydrogen halide to the hydrocarbon feed is at least 1:1 and the molar ratio of hydrogen halide to metal halide catalyst ranges from about 10:1 to about 40:1. The preferred catalyst is aluminum chloride or aluminum bromide. The preferred solvent is hydrogen chloride or hydrogen bromide.
