Abstract: A self-curing water dispersed copolymer particularly useful for coatings for interiors of beverage containers comprises a self-curing water dispersed copolymer of polymerized ethylenic monomers, including alkylol acrylamide monomer and functional monomer, produced by copolymerizing the monomers in the presence of an epoxy phosphate additive.
Abstract: Improved catalyst is made by including in a grind charge of cupreous particulates a small proportion of a hydroxide of Period IV metal having Atomic Number between 24 and 30, e.g. iron III oxide monohydrate. Said grind charge contains a major proportion of cuprous and cupric oxides, a minor proportion of elemental copper, and up to about 10% of promoter material. Such charge is subjected to high energy comminution with concomitant crystal lattice distortion. The catalyst is useful for the production of alkyl and aryl halosilanes.

Abstract: The invention pertains to sprayable latex polymers produced by step-wise polymerization of ethylenically unsaturated monomers comprising alkylol acrylamide monomer, functional monomers, and other monomers, wherein the alkylol acrylamide monomers are copolymerized in the second stage monomer addition to preferentially locate alkylol acrylamide groups in the surface portion of the latex polymer particles.
Abstract: The present invention resides broadly in a method for applying water soluble coatings to highly water soluble core particles selected from the group consisting of sugar, salt, yeast, and solid acidulants, comprising the steps of selecting core particles of fine particle size such that a preponderance of the particles pass through a 16 mesh screen, U.S.

Abstract: The present invention relates to a non-dairy, fat-free, dry blend suitable for reconstitution with milk, to provide an imitation buttermilk product having the color, flavor, consistency and texture of cultured buttermilk. The dry blend of the present invention comprises, as essential ingredients, a major amount of maltodextrin; a minor amount of a milk soluble hydrocolloid gum; an acidifying amount of a food grade acid, of which a flavoring amount is acetic acid; and other flavorants and colorants. On reconstitution with milk, a stable product is obtained despite low pH in the range of about 4.2-4.6.

Abstract: A polymeric composition useful for interior coatings for beverage containers comprises a polymeric mixture of epoxy-acrylic copolymer and epoxy phosphate ester.
Abstract: A self-curing water dispersed emulsion or solution polymerized polymer comprises copolymerizing ethylenically unsaturated monomers including (i) alkylol acrylamide monomer, (ii) functional monomer such as carboxyl, hydroxyl, amine, or amide functional monomer, (iii) phosphated monomer, and (iv) other ethylenically unsaturated monomer.
Abstract: The composition comprises an aqueous polyelectrolyte polymer intermixed with a phosphated polymer and a self-curing water dispersed polymer containing copolymerized functional monomer and alkylol acrylamide monomer. The polyelectrolyte polymer is produced by copolymerizing ethylenically unsaturated monomers, including hydroxyl or carboxyl monomers in the presence of an ionizing agent.
Abstract: A protective surface coating composition containing polyol, glycoluril, and emulsion polymer can be heat cured to produce cured films on substrates. The coating is particularly useful as wood coatings.
Abstract: The present invention relates to liquid soaps for use in paper re-cycling and other industrial cleaning or scouring processes.The liquid soap comprises an aqueous partially saponified mixture comprising 1 part of pine oil (a mixture of terpene alcohols and hydrocarbons) and from 1 to 20 parts of a soap-making fatty acid, such as tall oil or distilled oil. The mixture is preferably saponified by use of 30% sodium hydroxide solution. The liquid soap may contain less than 10% water.
Abstract: There is provided an improved process for producing biologically active arylterpenoid compounds useful to inhibit eclosion of pupae, e.g., fly pupae or mosquito pupae. The process is characterized by reacting a terpenoid material having a terminal unsaturated linkage, e.g., dihydromyrcene (3,7-dimethylocta-1,6-diene) with a lower alkyl Grignard reagent, e.g., n-propyl magnesium chloride to form a Grignard exchange product. The exchange product is then benzylated. Either a benzyl halide, e.g., p-isopropylbenzyl chloride, or a benzaldehyde, e.g., p-isopropylbenzaldehyde may be used. These compounds are specifically described in U.S. Pat. No. 4,002,769. They contain also a lower alkoxy group, e.g., methoxy. This can be introduced prior to the formation of the Grignard exchange product or at a later stage in the operation. Use of the exchange-type Grignard reaction enables elimination of several steps when producing the arylterpenoids from pinene as the terpene source, and consequent costs.

Abstract: Non-gelled compositions containing hydroxy ester copolymer having carboxyl groups and substantially free of oxirane groups and the method of making them are disclosed which are the esterification reaction product of(A) acidic addition copolymer; and(B) epoxy resin including aromatic polyether containing oxirane groups in which the epoxy resin comprises at least 40% of the total resin solids and contains insufficient oxirane groups to react with all of the carboxyl groups in the copolymer; in which esterification is conducted in the presence of higher than the normal amount of amine catalyst, i.e., 1.5% or more. The resulting composition is neutralized with amine, is self-emulsifiable in water and is useful for coatings, e.g., for cans.

Abstract: Provides new and improved water-reducible coating compositions and methods of making them. Three preferred processes are disclosed. These differ in the manner of incorporating and chemical nature of an extender polymer.Broadly, the process of the invention is one for forming an aqueous dispersion of a fluent resinous composition ofa. a mixture in an organic solvent of(i) an ionizable graft polymer of an epoxy resin and an addition polymerized resin, the addition polymerized resin being bonded to aliphatic backbone carbon atoms of the epoxy resin by carbon-to-carbon bonds, and(ii) an extender resin;b. an aqueous vehicle, andc. an ionizing agent;the ionization present from said combined components being sufficient to establish the components as a dispersion in the aqueous vehicle, and then addition polymerizing a quantity of addition polymerizable monomer, under addition polymerizing conditions, in said aqueous dispersion, the aqueous dispersion serving as a vehicle therefor.

Abstract: Sanitary coatings based on self-emulsifiable epoxy ester copolymers are produced by esterifying a solvent-soluble carboxyl polymer with an epoxy resin in an organic resin and in the presence of at least about 2% amine catalyst to provide a carboxyl-functional epoxy polymer which can be reacted with a base and dispersed into water.
Abstract: There is provided a new method for analysis of the size and/or distribution of particles emanating from a mother liquid by sedimentation in a rotating disc centrifuge, particularly a photosedimentometer. The method is characterized in that the spin fluid or medium is formed externally of the disc as distinct from being formed within the disc while it is rotating. The externally prepared spin medium is formed from at least two miscible liquids of different densities for example, methanol and water, in a manner such that they are substantially incompletely mixed whereby a density gradient is established in the spin medium. Thereafter the spin medium is injected into the disc while spinning at a given speed, and later the mother liquid is injected. Results are closely comparable to the buffered line start method described in U.S. Pat. No. 3,475,968.
Abstract: A process and a product produced thereby, for forming rod or bar or tube stock or strip, comprising a sheath and a densified dispersion strengthened metal core. Powdered dispersion strengthened copper is put into a metal can and compressively reduced to size and density. The relationship between the tensile strength of the core when fully densified and the cold worked tensile strength of the can is important to the nature of the product.
