Abstract: A (meth)acrylate functional copolymer is useful as a dispersant for solid particulates in paints, inks and coatings. The copolymers have (meth)acrylate functionality positioned pendant to the polymer chain. Also positioned pendant to the polymer backbone chain are non-(meth)acrylate-functional hydrophobic and/or hydrophilic pendant groups. The copolymers are useful as dispersants in dispersions of particulate solids in organic media and aqueous media, such in paints and printing inks.

Abstract: A visual indicating paste composition is provided which is capable of producing a detectable color change upon contact with an aqueous liquid. The paste composition includes: an indicator dye capable of changing color in the pH range between about 3 and about 11; an inorganic base capable of being converted to a more basic substance upon reaction with water; a liquid carrier (such as a polyalkylene glycol carrier); optionally, a gelling agent such as silica gel; and a proton donating compound such as a carboxylic acid or organosulfonic acid. When applied to a measuring probe, the paste composition is particularly adapted for detecting the water level in the bottom of tanks and delivery systems containing a fuel such as gasoline by producing a clear detectable color change without bleeding or run-off upon contact with an aqueous liquid. The paste composition exhibits long shelf life and improved water tolerance.

Abstract: Useful articles, such as coatings, adhesives, printed graphics, 3D printed articles and molded articles are prepared by curing compositions containing one or more salts of ethylenically unsaturated carboxylic acids comprising six or more carbon atoms, one or more multifunctional (meth)acrylate oligomers and one or more mono(meth)acrylate esters of alcohols which, when polymerized as homopolymers, have glass transition temperatures of at least 50° C.

Abstract: Free radical-curable halogenated polyethylene polymer compositions, which are crosslinked with the aid of a crosslinking monomer selected from the group consisting of calcium diacrylate and calcium dimethacylate coagents and, optionally an alkyl aminoalkyl phenol vulcanization inhibitor, are provided. The compositions of the invention yield cured rubber articles with markedly improved tensile strength and scorch resistance. Processes for producing a cured rubber article from the disclosed free radical-curable elastomeric compositions and cured compositions prepared from such curable compositions are also provided.

Abstract: The residual level of N-vinylcarbazole in polyvinylcarbazole has been reduced to an amount less than 25 ppm by treatment of a solution of the polyvinylcarbazole with a strong acid. The polymer can be recovered in pure form by precipitation of the polymer from solution with a non-solvent.

Abstract: Thermoplastic elastomers made by copolymerizing macromolecular monomers with alkoxyalkyl acrylates serve as binders for solid propellants which binders have high burn rates and increased insensitivity over conventional binders. The preferred alkoxyalkyl acrylate is methoxyethyl acrylate.
