Abstract: This invention is concerned with compositions of granular sodium tripolyphosphate (STPP) and their manufacture, which are suitable for use in the manufacture of automatic dishwasher detergents. The granular STPP compositions contain an overall 30 to 40% by weight of the STPP Phase I modification and no more than 5% of the granules composing the composition shall be of both +50 mesh size and under 25% Phase I concentration. Particle size of the total composition is 10% maximum of both +20 mesh and -100 mesh fractions. Apparent density is 0.7 to 0.9 grams per cubic centimeter. Such compositions are made by using only STPP materials in the 30 to 40% range or by mixing -50 mesh fractions of lower Phase I material with coarser fractions of higher Phase I material so that Phase I content of the total mixture is 30 to 40%.

Abstract: A coating composition is provided which is suitable for the protection of corrodible metallic surfaces. The coating composition includes a binder and a filler, with the filler present in an amount sufficient to impart corrosion-resistant characteristics to the coating composition. The filler comprises conductive metal particles and particles of a metal composition which comprises silicon and at least one active metal. The metal composition can be an alloy of silicon with an active metal which is unstable when introduced alone into water or a silicide of an active metal which is unstable when introduced alone into water.

Abstract: A method is provided for extending the life of transition metal-based cathodes used in chlor-alkali diaphragm cells by adding a small amount of a reducing agent, such as Na.sub.2 SO.sub.3 or urea, to the electrolytic solution during periods of interrupted current flow to the cell. The reducing agent reacts with the sodium hypochlorite which is dissolved in the electrolytic solution to prevent the oxidation, and hence dissolution, of the transition metal in the cathode coating.

Abstract: In filter press electrolytic cell assemblies, gasketing materials are frequently used for sealing the cell contents between individual frames. An improved design of gasket is disclosed, having a bulb profile at one surface with a hollow or indented profile on the opposite. Use of this specific profile gasket, positioned in properly molded or machined sealing grooves in the mating surfaces of electrolytic cell frame members, permits repeated disassembly and reassembly of cell frame components without leakage of electrolytic fluids between cell compartments, or leakage from cell interior to exterior.

Abstract: The present invention relates to production of vinyl halide-polyolefin graft copolymers by a liquid phase bulk polymerization process wherein the process is carried out in the presence of a diluent. Suitable diluents preferably have vaporization pressure characteristics, within 100 psi., and similar liquid state viscosity, as vinyl halide monomer. The diluents are soluble in vinyl halide monomer under reaction conditions and are inert to the polymerization mass. The diluents are straight or branched chain, or cyclic saturated hydrocarbons having from about 3 to about 15 carbon atoms and, more preferably, from about 4 to about 8 carbon atoms. Particularly useful diluents are n-propane, n-butane, isobutane or mixtures thereof. The diluents are utilized in amounts from about 0.2 to less than about 50.0 percent based upon the total weight of the reaction charge.

Abstract: Linear aromatic polyesters of bisphenols and dicarboxylic compounds are prepared by transesterification polymerization in either a fully continuous process or in a semi-continuous process wherein a first stage is conducted batchwise and a second stage is conducted in a continuous manner wherein the second stage employs a wiped film reactor. The processes are preferably conducted in the presence of a catalyst in liquid form, and further under conditions wherein the catalyst is introduced to the polymerization concurrent with the introduction of liquid phase reactants to avoid substantial heating of the reactants in contact with the catalyst prior to onset of the transesterification reaction. The products of the processes have an unexpectedly low polydispersity.

Abstract: A polymer blend capable of being molded to an impact resistant, substantially transparent or translucent article which comprises a vinyl halide homopolymer or copolymer, a conventional impact resistance enhancing polymer agent for polyvinyl halide wherein the monomer units consist essentially of methyl methacrylate, 1,3-butadiene and styrene residues and a thermoplastic block elastomer wherein the essential and predominant monomer units are the residue of a mono-alkenyl aromatic hydrocarbon and the residue of an alkadiene hydrocarbon. The thermoplastic elastomer is normally incompatible with the vinyl halide polymer or copolymer. The vinyl halide polymer or copolymer constitutes the major proportion of said blend and the block and methacrylate polymers together constitute a minor proportion of the composition. The weight ratio of block polymer to methacrylate polymer is about 1:5 to about 5:1.
