Abstract: The present technology generally relates to emulsion polymer latexes, particularly those used in pressure sensitive adhesives, paints and coatings. Surfactant compositions of the present technology for use in forming at least one emulsion polymer latex comprise at least one branched surfactant, at least one sterically bulky surfactant, or a mixture of branched and sterically bulky surfactants. One preferred surfactant composition comprises at least one alkoxylated polyaryl substituted aromatic compound or at least one alkoxylated polyalkyl substituted aromatic compound. Another preferred surfactant composition comprises a mixture of at least one branched-alkyl sulfate and at least one ethoxylated polystyrylphenol. Another preferred surfactant composition comprises at least one sulfated polystyrylphenol.

Abstract: A barrier panel for enclosures and shield with a self-supporting framework of rigid tubes encompassing at least one through opening. The opening is enclosed by a cover sheet of flexible plastic film releasably secured to the framework by snap-on clips and a complementary retainer attached to a side face of the framework.

Abstract: A water spray nozzle for removing paint particles from air exhausted from a paint spray booth. The nozzle has an inlet and an outlet and at least two orifices therebetween which are of progressively diminishing size in a direction toward the outlet. The walls of the nozzle are designed to produce considerable turbulence of the water stream flowing through the nozzle and to produce a wide angle solid spray of water from the nozzle outlet.

Abstract: Polymer blends of ethylene-higher .alpha.-olefin-polyene (EPDM) polymers with highly unsaturated diene rubbers are cured using sulfur and a N,N-(higher alkyl) thiocarbamylsulfenamide as a vulcanization accelerator. The vulcanizates exhibit improved tensile strength, flex-heat build-up, and oil swell properties.

Abstract: Thiocarbamylsulfenamide compounds having alicyclic or heterocyclic groups are good fungicides and bactericides. The compounds exhibit good stability during storage, and are useful to prepare disinfectant compositions.
