    摘要: Water-soluble graft copolymers of acrylic acid and a watersoluble polyhydroxy polymeric compound, including water-soluble salts thereof, are useful as binders in the agglomeration of finely divided materials. The graft copolymers are especially useful as binders in the pelletization of minerals and ores, such as taconite.

    摘要: A dripless, water base paint containing a latex or rubber-like binder, a pigment, an aqueous vehicle for the pigment and binder, and a small quantity of Heteropolysaccharide-7, a novel heteropolysaccharide, in an amount sufficient to give the paint pseudoplastic properties. The paint may contain a small quantity of a water-soluble alginate in addition to the novel heteropolysaccharide. Process for forming a dripless, water base paint containing a latex or rubber-like binder, a pigment, and an aqueous vehicle for the binder and pigment. The process may include the formation of a pigment grind of the pigment in water prior to the addition of the latex binder, which comprises adding a small quantity of the novel heteropolysaccharide to the pigment grind and thereafter grinding the pigment which reduces the time required to obtain optimum dispersion of the pigment.

    摘要: PAPER REINFORCING AGENT COMPOSED MAINLY OF A POLYMER COMPOSITION WHICH INCLUDES A GRAFT POLYMER, A WATERSOLUBLE POLYSACCHARIDE, AND, IF NECESSARY, AN ACRYLAMIDE TYPE RANDOM COPOLYMER. THE GRAFT POLYMER IS THAT HAVING THE WATER-SOLUBLE POLYSACCHARIDE AS ITS BACKBONE POLYMER AND A COPOLYMER DERIVED FROM A MONOMER MIXTURE OF ACRYLAMIDE AND AN UNSATURATED CARBOXYKIC ACID, AS ITS BRANCH POLYMER; SAID RANDOM COPLYMER IS THAT WHICH IS DERIVED FROM THE AFORESAID MONOMER MIXTURE. THE WATER-SOLUBLE POLYSACCHARIDE CONTENT IS 5-22% BY WEIGHT BASED ON THE COMPOSITION. THE PAPER REINFORCING AGENT IS OBTAINED BY POLYMERIZING THE AFORESAID MONOMER MIXTURE IN THE PRESENCE OF THE WATER-SOLUBLE POLYSACCHRIDE, OR BY FURTHER ADDING THERETO A SUITABLE AMOUNT OF THE WATER-SOLUBLE POLYSACCHARIDE AMD/OR THE ACRYLAMIDE TYPE RANDOM COPOLYMER. THE REINFORCING AGENT EXHIBITS HIGH PAPER-REINFORCING PROPERTY EVEN IN A SMALL QUANTITY AND IS MARKEDLY CHEAPER THAN ANY OF THE KNOW ACRYLAMIDE TYPE PAPER REINFORCING AGENTS.

    摘要: IN THE CREAMING PROCESS FOR CONCENTRATING DILUTE AQUEOUS COLLOIDAL DISPERSIONS OF POLYTETRAFLUOROETHYLENE, USING A CREAMING AGENT NATURALLY-OCCURRING WATER-SOLUBLE COLLOIDS, IN THE PRESENCE AS STABILIZER OF NON-IONIC SURFACE ACTIVE AGENT TO OBTAIN A CONCENTRATED DISPERSION PHASE AND A SUPERNATANT AQUEOUS PHASE, FOLLOWED BY PHASE SEPARATION, VISCOSITY OF THE RESULTANT CONCENTRATED DISPERSION IS REDUCED, WITHOUT CONCOMITANT LOSS IN STABILITY, BY A PROCESS IMPROVEMENT WHICH COMPRISES ADDING AQUEOUS HYDROGEN PEROXIDE TO THE DISPERSIONS TO BE CREAMED IN AMOUNT OF ABOUT 2 TO 20 PARTS BY WEIGHT PER 100 PARTS OF CREAMING AGENT.
