Abstract: Stabilized, aqueous dispersions of multivalent metal humates are disclosed as a compatible and functional component in printing ink formulations.
Abstract: A backstand threading device to be mounted on a paper sheeter to permit an operator to move the device and himself along the length of the paper sheeter to thread each of the plurality of webs moving through the paper sheeter.
Abstract: A process of preparing a bleaching liquor with an improved stability involves mixing of magnesium ions and hydrogen peroxide prior to the addition of sodium hydroxide. The liquor may be used to bleach Kraft wood pulps, obtaining higher brightness levels.
Abstract: Silicone rubber matrices are used to contain and dispense volatile, organic liquids. The articles, as dispensors are improved by the use of silicone rubber matrices prepared by the curing of silicone fluids selected from the group consisting of polydiphenylsiloxane, polymethylphenylsiloxane, polymethyl-3,3,3-trifluoropropylsiloxane and a polydimethylsiloxane wherein 5% or more of the methyl groups of the polydimethylsiloxane are replaced by phenyl or polar aliphatic groups. Higher loadings of the organic liquid into the rubber matrix are achieved without syneresis occurring.
Abstract: Aqueous ink compositions are disclosed which are an admixture a colorant, a resin binder which is the Diels-Alder adduct of maleic anhydride and 2,3- and 6,7-poly(alloocimene) or the partial-ester thereof and a solvating proportion of water. The inks are useful in flexographic and gravure printing.
Abstract: The disclosure is of an improved process for the hydrohalogenation of myrcene in the presence of a catalyst, which comprises carrying out the hydrohalogenation in the presence of an alcohol.
Abstract: The disclosure is of an improved process for the hydrohalogenation of a conjugated diene in the presence of a catalyst, which comprises carrying out the hydrohalogenation in the presence of an organic quaternary salt.

Abstract: Silicone rubber matrices are used to contain and dispense volatile, organic liquids. The articles, as dispensors are improved by the addition of a compatibilizing agent to reduce migration of the organic liquid out of the matrix in the form of liquid drops or films. Higher loadings of the organic liquid into the rubber matrix are achieved without syneresis occurring.
Abstract: Organic esters of hypophosphorous acid are used to catalyze the esterification of rosin with a polyol. The method is an improvement in that reaction time is shortened and the ester product exhibits improved heat stability.
Abstract: Halogenated poly(alloocimene) is described. The polymer is useful in coatings as barrier resin, slow release material for pesticides and the like.
Abstract: A novel class of alloocimene polymers have been prepared which are comprised of a mixture of polymer chain units of 2,3-alloocimene and 6,7-alloocimene. The novel polyalloocimenes of this invention are prepared by polymerizing alloocimene in a reaction mixture which contains a catalyst system comprised of a metal such as sodium and an aliphatic or cycloaliphatic ether such as 1,2-dimethoxyethane. The polyalloocimenes of this invention have a majority of the residual unsaturation present in pendent dimethylbutadienyl groups. The polyalloocimenes of this invention are useful in of themselves as film forming binders for inks, as tackifiers for hot melt adhesive and the like. The polyalloocimenes of this invention are also especially useful as intermediates. The presence of the substantial amount of unsaturation and particularly the conjugated unsaturation of the pendent groups make the polyalloocimenes of this invention exceptionally reactive.
Abstract: Phosphorous acid is used to catalyze the esterification of rosin with a polyol. The method is an improvement in that reaction time is shortened and the ester product exhibits improved color and oxygen stability.
