  • Patent number: 9138967
    Abstract: Wood laminates may comprise a plurality of wood substrates and an adhesive disposed between at least a portion of at least two of the wood substrates, the adhesive comprising a substituted cellulose ester that comprises a cellulose polymer backbone having an organic ester substituent and an inorganic ester substituent that comprises an inorganic, nonmetal atom selected from the group consisting of sulfur, phosphorus, boron, and chlorine. In some instances the adhesive may be substantially formaldehyde-free.
    Type: Grant
    Filed: September 24, 2012
    Date of Patent: September 22, 2015
    Assignee: Celanese Acetate LLC
    Inventors: Michael Combs, Thomas Garrett, Chad Prunesti, Martin Jakob, Yi (Julie) Li, Xiaoyan Tu
  • Patent number: 9090045
    Abstract: Engineered wood may be produced with substituted cellulose ester adhesives. For example, an engineered wood may comprise a plurality of wood substrates that independently comprise a lignin-containing material (e.g., wood dust, wood particles, wood chips, and the like), the plurality of wood substrates being adhered together with an adhesive that comprises a substituted cellulose ester that comprises a cellulose polymer backbone having an organic ester substituent and an inorganic ester substituent that comprises an inorganic, nonmetal atom selected from the group consisting of sulfur, phosphorus, boron, and chlorine.

  • Publication number: 20150203723
    Abstract: A substituted cellulose ester having a cellulose backbone with an organic ester substituent and an inorganic ester substituent derived from the inorganic ester oxoacid catalyst may be utilized in adhesive compositions and articles produced therewith. Producing a substituted cellulose ester may, in some embodiments, involve providing a cellulose ester mixture that comprises a cellulose ester and a solvent; and hydrolyzing a mixture that comprises the cellulose ester mixture, water, and an inorganic ester oxoacid catalyst so as to yield a substituted cellulose ester having a cellulose backbone with an organic ester substituent and an inorganic ester substituent derived from the inorganic ester oxoacid catalyst.
