Abstract: Ethylene and allyl- or vinylsilanes are efficiently copolymerized by certain late transition metal complexes containing selected bidentate or tridentate ligands. The resulting novel polymers may be crosslinked by moisture when vinylsilane contains groups bound to silicon which are hydrolyzable. The polymers are useful for wire coating, crosslinked foams, pipes, and other uses.

Abstract: Transition metal complexes of selected monoanionic phosphine ligands, which also contain a selected Group 15 or 16 (IUPAC) element and which are coordinated to a Group 3 to 11 (IUPAC) transition metal or a lanthanide metal, are polymerization catalysts for the (co)polymerization of olefins such as ethylene and ?-olefins, and the copolymerization of such olefins with polar group-containing olefins. These and other nickel complexes of neutral and monoanionic bidentate ligands copolymerize ethylene and polar comonomers, especially acrylates, at relatively high ethylene pressures and surprisingly high temperatures, and give good incorporation of the polar comonomers and good polymer productivity. These copolymers are often unique structures, which are described.

Abstract: Mixtures of different polyolefins may be made by direct, preferably simultaneous, polymerization of one or more polymerizable olefins using two or more transition metal containing active polymerization catalyst systems, at least one of which contains cobalt or iron complexed with selected ligands. The polyolefin products may have polymers that vary in molecular weight, molecular weight distribution, crystallinity, or other factors, and are useful as molding resins and for films.

Abstract: Catalysts for the polymerization of olefins are provided. The catalysts comprise: (a) a first active polymerization catalyst which is a Fe or Co complex of a ligand of the formula: wherein: R1, R2 and R3 are each independently hydrogen, hydrocarbyl, substituted hydrocarbyl, or an inert functional group; R4 and R5 are each independently hydrogen, hydrocarbyl, an inert functional group or substituted hydrocarbyl; and R6 and R7 are aryl or substituted aryl; and (b) a second active polymerization catalyst which contains one or more transition metals; and (c) a catalyst support.

Abstract: The inhibition of proteins synthesis by an antisense RNA-tRNA complex which is capable of inhibiting translation is described. Under certain conditions, growth of organisms is inhibited by inhibition of non-specific translation by an antisense RNA construct to a tRNA target. In vitro, cell-free inhibition of viral protein translation is described. Transformed microorganisms are disclosed. The invention has applicability in the control of cell growth, such as viruses, bacteria, infected cells, or tumor cells. The invention is useful in animal and plant fields.

Abstract: A device and method for treating hand-involved habits, including smoking, hair-twirling, nose-picking, nail-biting, skin-pulling, and the like, is disclosed. The invention consists of a form-fitting barrier placed on the hand of a patient. The barrier is made of a fabric which is generally form fitting and moves with the hand on which it is placed. The barrier is preferably in the form of a glove wherein the second and third digits are substantially inseparably joined together and webbing connects the third and fourth digits and the fourth and fifth digits. An insert portion of the barrier reduces ease of contact between the connected second and third digits and the thumb.
