The benzoxazole resin precursor further comprises a second repeating unit obtained by reacting a bisaminophenol compound not having a diamondoid structure and a dicarboxylic acid compound not having a diamondoid structure. Also disclosed is a resin film comprising the resin composition.Type: ApplicationFiled: September 21, 2006Publication date: August 27, 2009Inventors: Takashi Enoki, Atsushi Izumi, Hiromi Oki, Yukiharu Ono, Kazuyoshi Fujita

Publication number: 20090165978Abstract: Compositions comprising a blend of two or more paper strengthening agents have improved stability compared with previously known paper strengthening agents. One component is a polymeric paper strengthening agent, preferably a wet strengthening agent. The other component is a stabilized polyacrylamide prepared by (1) reacting a first portion of glyoxal with a polyacrylamide having pendant amide groups to form a first reaction mixture comprising polyacrylamide; (2) adding an acid to the first reaction mixture to form a second reaction mixture having a reduced pH and comprising the polyacrylamide; and (3) adding a second portion of glyoxal to the second reaction mixture to form the stabilized polyacrylamide. If desired, an aldehyde scavenger can be included in one or more of step (1), step (2), step (3), or the stabilized polyacrylamide. Such compositions can be used to enhance the strength of paper, particularly the wet strength of paper.Type: ApplicationFiled: November 21, 2008Publication date: July 2, 2009Applicant: Georgia-Pacific Chemicals LLCInventors: Cornel Hagiopol, Yuping Luo, David F.

Publication number: 20090142601Abstract: A functional aspartate prepared by A) reacting an aziridine with a Michael-acceptor molecule to form an aziridinyl aspartate, and B) reacting the aziridinyl aspartate with an active hydrogen containing compound to form the functional aspartate. The functional aspartate can be used in adhesive, sealant or coating compositions that also include an isocyanate functional material. The composition can be used in a method of bonding a first substrate to a second substrate that includes applying a coating of the above-identified adhesive composition to at least one surface of the first substrate or the second substrate, and contacting a surface of the first substrate with a surface of the second substrate, where at least on of the contacting surfaces has the coating applied thereto. The composition can also be used to coat substrates.Type: ApplicationFiled: January 15, 2009Publication date: June 4, 2009Inventors: Karsten Danielmeier, Douglas A.
