Abstract: Improved viscosity maintenance properties and high demulsibility values are provided by asphalt-in-water emulsions; e.g., RS-2 comprising in combination asphalt, emulsifiers and polyacrylamides having molecular weights above about 100,000.

Abstract: This invention relates to emulsion type adhesive compositions which include a metal neutralized sulfonated elastomeric co or terpolymer, wherein the neutralized sulfonated copolymer has about 5 to about 250 meq. of neutralized sulfonate groups per 100 grams of the neutralized sulfonated copolymer, and less than about 200 parts by weight of a hydrocarbon resin of a petroleum or coal tar distillate, having about 5 to 6 carbon atoms, the hydrocarbon resin being composed of aliphatic dienes and monoolefins per 100 parts by weight of the neutralized sulfonated co or terpolymer.

Abstract: Delayed action setting of a composition comprising an anionic latex of a film forming polymer by addition of a delayed action setting agent characterized in that the setting agent is a compound containing a multivalent metal cation having defined solubility characteristics in a quantity not greater than 2.5% wt/wt on total composition and not greater than 11% wt/wt based on film forming polymer solids in the composition.

Abstract: This invention provides a non-gelling water-in-oil high solids slurry dispersion of water-soluble polymer.The slurry dispersion composition contains between about 40-80 weight percent of water-soluble polymer, and is prepared by dehydrating a water-in-oil dispersion of synthetic water-soluble polymer, and then slurrying a quantity of finely divided water-soluble polymer into the dehydrated dispersion.

Abstract: Quaternized ammonium synthetic polymers having a solution viscosity, as measured on a 1% solution in deionized water at 25.degree. C. using a suspended level viscometer of from 1 to 500 cs are used as dispersing agents in aqueous slurries of water and solid particulate carbonaceous material.

Abstract: This invention relates to pressure sensitive adhesive compositions which includes a hydrogenated block copolymer such as Kraton G, about 25 to about 250 parts by weight of a hydrocarbon resin of a petroleum or coal tar distillate, aliphatic dienes and mono- and diolefins, cyclic olefins of 5 or 6 carbon atoms and hydrogenated poly cyclics per 100 parts by weight of the hydrogenated block copolymer, and about 25 to 200 parts by weight of a polybutene or polyisobutylene per 100 parts of the hydrogenated block copolymer, wherein said mixture of Kraton G, said hydrocarbon resin and said polybutene or polyisobutylene are dissolved in a non-reactive solvent at a concentration level of about 5 to about 25 grams per 100 mil of non-reactive solvent.

Abstract: Quick setting, anionic bitumen emulsion compositions, suitable for road paving, recreational surfaces, etc., are formulated by emulsifying the bitumen in water with an ammonium or alkali metal salt of a hydrocarbon-substituted sulfuric, sulfonic, phosphoric or phosphonic acid emulsifier, mixing the emulsion with a fine aggregate and, prior to spreading the aggregate emulsion mixture, introducing an alkaline earth metal set initiator. The resulting composition rapidly breaks to a hard cohesive structure, so as to permit early use by traffic.
