Patent number: 7507473Abstract: A unique primer emulsion chemistry yields excellent adhesion of polyethylene terephthalate (PET)resin to clay coated paperboard (with high starch content) at reduced coatweights of the primer emulsion and the resin as compared to other primer and tie-resin chemistries currently employed for moisture barrier applications. A primer used for adhesion enhancement is an ammonium catalyzed, self-crosslinking copolymer of ethylene-vinyl acetate with N-methylol acryl amide functional groups attached to a polymer backbone. Use of the primer in amounts up to about 0.5 pounds per ream permits PET coatweights of as low as 10-12 lbs per ream and lower for some applications.Type: GrantFiled: August 15, 2007Date of Patent: March 24, 2009Assignee: International Paper CompanyInventors: Ladislav Bednarik, Vivek Rohatgi, David V Reed

Publication number: 20090075540Abstract: The present invention is generally directed to adhesive compositions comprising selected ratios of crystalline and amorphous polymers. In some versions of the invention, polymers capable of existing in different configurations (e.g., a polymer such as polypropylene which can exist in an atactic, syndiotactic. or isotactic configuration) is used to prepare adhesives of the present invention. As an example, a selected amount of isotactic polypropylene is blended with a selected amount of atactic polypropylene to prepare an adhesive composition having one or more performance properties (e.g., bond strength) that are superior to the performance properties of a conventional hot-melt adhesive.Type: ApplicationFiled: September 16, 2008Publication date: March 19, 2009Applicant: KIMBERLY-CLARK WORLDWIDE, INC.Inventors: Peiguang Zhou, Timothy James Blenke

Publication number: 20090075107Abstract: Corrosion-resistant adhesive compositions are provided. The compositions are useful for bonding together plies in multi-ply cellulosic fibrous structures. Multi-ply cellulosic fibrous structures incorporating the adhesives, products produced from such structures, and methods of producing the structures are also disclosed. The adhesive compositions incorporate a polyvinyl alcohol polymer and a corrosion inhibitor. The adhesive compositions may be sprayed or coated onto the cellulosic structures to bond layers of the structure to each other. The corrosion-resistant adhesive compositions are useful for preventing corrosion in the various devices used for handling and application of the adhesives such as spray equipment and applicator rolls. The cellulosic fibrous structures may be used to produce a variety of products including paper towels, toilet tissue, facial tissue, napkins, and other absorbent materials.Type: ApplicationFiled: November 20, 2008Publication date: March 19, 2009Inventors: Bart Hedrick, Eduardo Romero Nochebuena

Patent number: 7435477Abstract: A particulate water absorbent contains a water absorbent resin as a main component, the water absorbent resin being a crosslinked polymer of a water-soluble unsaturated monomer. The water absorbent resin is particular in shape and contains particles of a particle size in a range of not less than 106 ?m and less than 850 ?m in an amount of not less than 90 mass percent with respect to the total mass of the water absorbent resin contained in the particulate water absorbent. The particulate water absorbent has a first salt concentration absorption index of not less than 0.60 as measured by a formula below when ion exchange water is used as an aqueous solution of a constant salt concentration: (salt concentration absorption index)=(absorbency against a pressure of 4.83 kPa with respect to the aqueous solution of a constant salt concentration)/(absorbency against no pressure with respect to the aqueous solution of a constant salt concentration).Type: GrantFiled: February 9, 2004Date of Patent: October 14, 2008Assignee: Nippon Shokubi Co., Ltd.Inventors: Yoshifumi Adachi, Takahiro Kitano, Hirotama Fujimaru, Hiroyuki Ikeuchi, Katsuyuki Wada
