    摘要: The invention relates to a process for the preparation of low viscous, water soluble polymer dispersions on an aqueous basis with a high concentration of the active substance, containing a polymerizate A) synthesized from the monomeric components, hydrophobic monomers and optionally amphiphilic monomers, which exhibit an average molecular weight M.sub.w of at least 5.times.10.sup.5 Dalton and contain at least one polymeric dispersing agent D), where in a first step an aqueous dispersion PD) is prepared from the polymerizate A) and at least one polymeric dispersing agent D); in a second step an aqueous, highly concentrated dispersion PD') is prepared from the aqueous dispersion PD) by extracting the water; and in a third step an aqueous dispersion PD") with a high content of the active substance is prepared through the addition of an aqueous dispersion of at least one polymeric dispersing agent D) to the concentrated dispersion PD'), and where the second and third process step can be repeated in succession.

    摘要: The tearing strength of paper is improved by providing a furnish in which the fiber content is predominantly refined fiber with a minor amount, preferably 2 to 10 wt. %, of added unrefined fiber having incorporated therein a heat activatable bonding agent, particularly starch. The bonding agent adheres to and coats the added fiber without chemically reacting with the fiber. A cationic material, particularly polyethyleneimine, is premixed with the raw starch to cause it to adhere to the added fiber. During heat drying of the formed paper the starch is gelatinized to effect enhanced bonding of the added fiber.

    摘要: An antimicrobial additive is incorporated into the binding agent of a heavy-duty, kraft-type paper having the characteristics of substantial density, air impermeability, and improved printability. The antimicrobial additive migrates from within the binding agent onto the paper fibers to substantially eliminate growth of micro-organisms thereon.
