    Abstract: Multicomponent polyethylene resin compositions which are processable using conventional molding techniques (e.g., rotational molding, injection molding and blow molding) have been discovered which offer improved IZOD impact strength of the molded part. Multicomponent polyethylene compositions comprising a uniform composition falling within the area of a polygon ABCD bounded by points A(66.7, 33.3, 0), B(33.3, 0, 66.7), C(0, 0, 100), D(0, 100, 0) and excluding the composition defined by line AB have improved room temperature notched IZOD impact strength over that calculated for the components using an additive rule. For three component polyethylene compositions, a first component (a) comprising a polyethylene resin having a density of about 0.92 g/cc and a melt index of about 1 g/10 minutes, a second component (b) comprising a polyethylene resin having a density of about 0.96 g/cc, and a melt index of about 1g/10 minutes, and a third component (c) comprising a polyethylene resin having a density of about 0.95 g/cc and a melt index of about 17 g/10 minutes are preferred. One of the components can also be replaced by a post consumer recycled plastic.

    Abstract: An electrolytic cell (10) for the labeling of proteins, peptides and other organic molecules employs a cathodic half cell (12) and an anodic half cell (14) where a porous working electrode (28) is located in one half cell and a counter electrode (40) is located in the other half cell, the two half cells (12 and 14) being divided by a separator (26). A reference electrode (36) located in the half cell containing the working electrode (28), and placed outside the current path between the working electrode (28) and the counterelectrode (40) confers precise control of the working electrode potential, which allows the maximum rate of labeling to be achieved while minimizing oxidative damage to the protein, peptide or organic molecules. Saturation of the working electrode (28) with non-radioactive label coupled with a ratio of working electrode surface area to volume of half cell containing the working electrode (28) between 0.001 to 10 cm minimizes the problem of loss of activity of radiolabel due to adsorption on the working electrode (28).

    Abstract: Dispose a solid-phase metal on a surface of a porous ceramic compact that is at an angle with respect to the horizontal sufficient to allow molten metal formed from the solid-phase metal to rupture an oxide layer that forms on, and at least partially supports, the molten metal. The solid-phase metal is heated to a temperature sufficient to melt the solid-phase metal and to allow the resultant molten metal to rupture the oxide layer. The molten metal flows through an opening in the metal oxide layer formed by the rupture and infiltrates the porous ceramic compact. The porous ceramic compact, containing the molten metal, is then cooled to a temperature whereby the molten metal solidifies, thereby forming a cermet.

    Abstract: Aqueous dispersions of ethylene/α,β-unsaturated carboxylic acid interpolymers (e.g., random ethylene/acrylic acid interpolymers) are formed using a mixture of bases at a concentration of at least 0.2 equivalents of base per mole of α,β-unsaturated carboxylic acid. The dispersions have at least 10 weight percent dispersed solids and not more than 1 weight percent of the initial polymer in non-dispersed form. Preferred bases for use in forming the dispersions are ammonium hydroxide and/or alkali metal hydroxides. A mixture of ammonium hydroxide and potassium hydroxide is especially preferred for forming the dispersions with ethylene/acrylic acid interpolymers at an ammonium hydroxide: acrylic acid molar ratio of 1:1 and a potassium hydroxyde:acrylic acid molar ratio in the range of 0.6-0.8:1. The dispersions are particularly useful in forming thin coatings of adhesive on substrates, such as paper and metal foil, using conventional techniques.
