Abstract: Clear, elastic, water gels and gel-forming compositions are based on potassium-sensitive carrageenan in the form of an alkali metal or an ammonium salt and a water-soluble potassium salt. Addition to the composition of calcium-sensitive carrageenan, also in the form of an alkali metal or an ammonium salt, imparts freedom from syneresis. The water gels and the gel-forming compositions are characterized by essentially complete freedom from polyvalent metal cations.

Abstract: Cementitious structures characterized by improved durability and weather resistance are obtained by: Incorporating alkyl and alkenyl succinic acids, their anhydrides, acid esters, acid amides, halogenated compounds and salts, into cementitious mixtures prior to setting; applying said succinic compounds onto concrete subsequent to setting; or by a combination of the forgoing steps; said alkyl and alkenyl substituents containing from 8 to 40 carbon atoms.

Abstract: Polymers are flame-retarded by novel combinations of additives comprising:A. a specified compound of iron, cobalt, nickel, tin or antimony,B. an alkali metal chloride, bromide or iodide, andC. an organic acid or inorganic acid salt.Alternatively, additive (c) may be an integral part of the polymer in whole or in part.

Abstract: New flame-retarded rubber and plastic compositions are disclosed which are economical to produce and which exhibit increased flame-retardance and reduced toxicity. Generally, these new compositions comprise a copolymer of acrylonitrile-butadiene rubber or a terpolymer of acrylonitrile, butadiene and styrene, a bromine- or chlorine-containing organic fire-retardant additive, and an iron compound selected from a specified group.

Abstract: This invention relates to a solution process for preparing copolymers of a conjugated diene hydrocarbon and a vinyl-substituted aromatic hydrocarbon using a potassium-modified organolithium catalyst. The Li/K molar ratio is varied depending upon whether a random or pseudorandom copolymer is desired and depending on whether an aliphatic hydrocarbon or aromatic hydrocarbon solvent or a mixture of such solvents is used. The invention includes the pseudorandom copolymers formed by the process of the invention, such copolymers being characterized, in part, by having blocks with two to four units of the vinyl-substituted aromatic hydrocarbon interspersed throughout the copolymer chain.

Abstract: This invention relates to an improved golf ball cover comprised of an ionomer based upon the copolymers of, e.g., ethylene and acrylic or methacrylic acid and a chlorosulfonated polyethylene. Covers made in accordance with this invention exhibit high durability features.

Abstract: Disclosed are new chemical compounds namely 1,4-dialkanols of octahydrothieno[3,4-b]pyrazine 6,6-dioxides and 4-alkanols of octahydrothieno[3,4-b]pyrazine 6,6-dioxides, the use of such compounds in the production of polyurethanes, and methods of making such compounds.

Abstract: Thermoplastic copolymers are formed by the interaction of a 4-mercaptophenol and a dihalo-substituted aromatic sulfone of the structureX--phenylene-SO.sub.2 2-phenylene) .sub.y X, wherein y is 1 or 2.

Abstract: Polymeric bromine-containing phosphoramidate polyols are obtained by reacting bromine with spirocyclic phosphoramidites and thereafter reacting the brominated products with a polyol, in the presence of an acid acceptor. The novel viscous polymers thus produced react with polyisocyanates to produce polyurethanes. Polyurethanes so made are characterized by improved flame-retardant properties compared with conventional polyurethanes.
