  • Publication number: 20090229776
    Abstract: The invention relates to a tissue product comprising (a) tissue fibrous web incorporated throughout the tissue product; (b) a temporary wet strength agent capable of forming hemi-acetal bonds with the fibers of the web to prevent immediate degradation of the web when the tissue product contacts water; and (c) a composition containing a degrading agent selected from the group consisting of alkaline agents, oxidizing agents, nucleophilic agents, and combinations thereof; such that the tissue product has at least one surface and the degrading agent is located substantially throughout the surface of the fibrous web in an amount sufficient to make the fibrous web exhibit (i) an immediate wet tensile strength of at least 90% of the wet strength as compared to a web that does not contain a degrading agent and (ii) a wet soak decay that is at least a ten point improvement as compared to a tissue fibrous web that does not contain a degrading agent.

  • Publication number: 20090223645
    Abstract: A composition comprising a polymer that is a reaction product of: a copolymer backbone comprising; (i) at least one acrylamide component, (ii) at least one co-monomer, (iii) at least one initiator and (iv) at least one chain transfer agent; and at least one cellulose reactive agent; wherein the copolymer backbone and cellulose reactive agent are combined with water to form a solution wherein the concentration of the copolymer backbone is about 0.1 to about 19% by weight based on the total weight of the solution. A process to make high solids copolymer backbone with low molecular weight and narrow molecular weight distribution has also been developed by a continuous polymerization process under refluxing conditions. In this process, a mixture of the acrylamide, co-monomer and chain transfer agent and the initiator are simultaneously and continuously added to a heel of water.

  • Publication number: 20090071618
    Abstract: A composition comprising a functionalized water-soluble, cationic, thermosetting, cellulose reactive polymer with a doubly structured backbone that is the reaction product of: (a) a copolymerized (i) acrylamide component, (ii) cationic co-monomer component and (iii) at least one multifunctional crosslinking monomer component; and (b) a cellulose reactive agent component; such that the acrylamide component, the cationic co-monomer component, the multifunctional crosslinking monomer component, and the cellulose reactive agent component are in an amount sufficient amount to produce a polymer that imparts strength to a fibrous substrate when the polymer is added to paper stock during a papermaking process. The invention also relates to methods for making and using such a composition.

  • Patent number: 6117938
    Abstract: The invention provides blends of high molecular weight, water-soluble cationic structured polymers with high molecular weight, water-soluble, cationic polymers which either are linear or which have a lower degree of structure. The blends are useful for dewatering dispersions of suspended solids, achieving good dewatering rates at relatively low dosage levels.
