Abstract:
Free radically crosslinked, electrically conductive compositions exhibiting a highly stable volume resistivity comprise an olefin multiblock copolymer (OBC) and a conductive filler, e.g., a conductive carbon black. These compositions exhibit a highly stable volume resistivity relative to a composition similar in essentially all aspects save that the OBC is replaced with a conventional polyethylene of similar density and melt index.

Abstract:
The present invention provides strategies for making cyclic triamines. Reactant media including certain precursors and/or certain types of catalysts can be converted into cyclic triamines with improved conversion and selectivity. The strategies can be incorporated into reactions that involve transamination schemes and/or reductive amination schemes. In the case of transamination, for instance, using transamination to cause ring closure of higher amines in the presence of a suitable catalyst leads to desired cyclic triamines with notable conversion and yield. In the case of reductive amination, reacting suitable polyfunctional precursors in the presence of a suitable catalyst also yields cyclic triamines via ring closure with notable selectivity and conversion. Both transamination and reductive amination methodologies can be practiced under much milder temperatures than are used when solely acid catalysts are used. Preferred embodiments can produce reaction mixtures that are generally free of salt by-products.
Abstract:
The invention provides a catalyst composition composed of a support portion and a catalyst portion. The support portion includes an acidic mixed metal oxide including a transitional alumina and a second metal oxide. The transitional alumina can comprise delta or theta alumina, in combination with other transitional phases, or an alpha or gamma alumina. The second metal oxide has a weight percentage that is less than the weight percentage of alumina. The catalyst portion is 25 weight percent or less of the catalyst composition and is composed of nickel and rhenium. The catalyst portion includes nickel in an amount in the range of 2 to 20 weight percent, based upon total catalyst composition weight, and there is no boron in the catalyst portion.
