Abstract: The present invention is directed to a benzoxazine-functionalized diene-based elastomer comprising polymer chains including repeat units which include conjugated diolefin monomers, such as 1,3-butadiene and isoprene. Additionally, said elastomer comprises at least one benzoxazine connected to a polymer chain via a spacer, wherein the spacer has a length ranging from 3 to 8 atoms. A further aspect of the present invention is directed to a rubber composition comprising such an elastomer, an article of manufacture comprising this rubber composition, and a method of making said benzoxazine-functionalized diene-based elastomer.

Abstract: Oxidative dehydrogenation of light paraffins, such as ethane at moderate temperatures (<500° C.) to produce ethylene without the formation of side products such as acetic acid and/or other oxygenated hydrocarbons is achieved using tellurium-free, multimetallic catalysts possessing orthorhombic M1 phase and other crystalline structures that have an important role for obtaining high performance catalysts for the oxidative dehydrogenation of ethane to ethylene. Such catalysts are prepared using thermal and hydrothermal methods.

Abstract: The present invention relates to the preparation of Multimetallic Anionic Clays (MACs) through a simple method, which are then shaped by spray-drying into microspheres with adequate mechanical properties, suitable to be fluidized. The microspheres are appropriate for application as additives in the Fluid Catalytic Cracking (FCC) process, i.e. blended with the conventional catalyst, to in situ remove sulfur oxides (SOx) from the combustion gases produced in the regeneration stage of the FCC process, when cracking sulfur-containing hydrocarbon feeds. An oxidation promoter is added to the MACs in order to promote the oxidation of SO2 to SO3, a key step in SOx removal, providing more efficient and versatile materials, which are apt to be used in atmospheres with variable oxygen concentration.

Abstract: A layered multimetallic mixed oxide (LMMO) is characterized by one or more diffraction peaks at 5<2?<15, preferably between 10<2?<15. The catalysts can be represented by the general formula: M1 M2 M3 O? wherein M1 is selected from the group of Ag, Au, Zn, Sn, Rh, Pd, Pt, Cu, Ni, Fe, Co, an alkaline metal, an alkaline earth metal, a rare earth metal, or mixtures thereof. M2 is selected from the group of Ti, Hf, Zr, Sn, Bi, Sb, V, Nb, Ta and P, or mixtures thereof. M3 is selected from the group of Mo, W and Cr, or mixtures thereof. ? depends on the amount and oxidation state or valence of the other components, also it depends on the starting materials, preparation method and the activation process, and where the catalyst exhibits at least one X-ray diffraction peak between 5<2?<15.

Abstract: To increase tire traction in snow, mud, etc., traction shoes are mounted so as to overlie the tread of a tire. The traction shoes are connected to a mounting bar which traverses the outside of a vehicle wheel and is held to the wheel by means of chain segments with hooks on the ends, the hooks engaging the back edges of the wheel rim support members.
