The polymer in accordance with the invention has the repeating unit (--A--NH--B--S--), wherein A and B are conjugated groups. The polymer proves to be readily soluble already in customary organic solvents, without the groups A and B having been provided with saturated substituents, and, after doping, has an electric conductivity of approximately 1 S/cm. The method yields semiconducting polymers in accordance with the invention, which have a high molecular weight and few topological defects.

Abstract: An alkaline aqueous cleaning composition for cleaning a substrate, e.g., a plastic or metal substrate, contaminated with industrial-type soil contaminants contains (i) an aqueous portion and (ii) an active-ingredient portion composed of (A) an alkalinity-providing agent and (B) a surfactant mixture containing (a) an active concentration of an N-octyl-2-pyrrolidone surfactant and (b) an active concentration of at least one aminocarboxylic acid surfactant. The active-concentration ratio of surfactant (a) to surfactant (b) is such as to provide the cleaning composition with the ability to remove a substantial portion of the contaminants from the substrate. At an active-concentration ratio of surfactant (a) to surfactant (b) of about 2.5:1, the surfactants have a synergistic effect on the industrial-soil-removing ability of the aqueous composition.

Abstract: The present invention is a powdered stain remover formulation which when mixed with water exhibits bleaching and stain discoloration properties together with the required detergency, and also exhibits mildewcide and bacteriocidal properties. The formulation includes calcium hypochlorite; a surfactant to promote detergency by emulsification, such as sodium dodecylbenzene sulfonate and a polyacrylic acid salt, such as sodium polyacrylate, to further promote cleaning by chelation. The stain remover formulation is applied to the stained surface by spraying, rolling or brushing. In this manner, water stains, tobacco, soot, mold, mildew and other stains are readily removed from the desired surface, such as sprayed textured walls and ceilings, tiles, masonry, fiberglass and plastic furniture.

Abstract: A transparent cleansing bar having a logo or other design or message printed on a dissolvable polymer material embedded at approximately the mid-point of the bar. The message is printed on both sides of a very thin sheet of dissolvable plastic material. The bar is formed from transparent modified soap material. The printed sheet is positioned between the two halves of the bar which form the transparent bar having the printed message at the midpoint. The message is viewable through the transparent bar. Upon normal use, the surface of the bar wears away. When the bar is worn or wasted to the midpoint and the printed polymer sheet is exposed to water, the printed sheet dissolves to avoid any disposal problems. An improved method for forming the transparent cleansing bar with a dissolvable, printable film also is disclosed.

These solutions are stable when stored in separate containers. As needed, the solutions are mixed together. This invention is effective for bleaching soil and for removing mold, applicable for cleaning, bleaching, sterilizing or deodorizing in either domestic or industrial use.

Abstract: The invention relates to bar compositions comprising an alkali metal salt of hydrophobically modified ethylenediaminetriacetic acid.

Abstract: Calcined ceramic powder is made by blending a precursor powder with a form of carbon such as carbon black and heating the blend in an oxygenated atmosphere. The carbon acts as a separator, preventing coalescence of the percursor powder during the calcining process. The blend is characterized by the presence of interstitial spacing between the particles of the carbon powder and the precursor powder. The carbon is eventually oxidized to carbon dioxide and/or carbon monoxide and volatilizes as such, leaving behind the calcined ceramic powder. In a preferred embodiment, the heating is effected by microwave radiation. The carbon absorbs the microwave radiation, heating up the precursor powder and calcining it to form the ceramic powder. Once all the carbon has been oxidized, no more microwave radiation is absorbed, and the heating stops, making the process self-limiting.
