  • What is cellulose acetate butyrate (CAB)?
  • Introduction Cellulose acetate butyrate (CAB), with the molecular formula of [C 6 H 7 O 2 - (OCOCH 3) X - (OCOC 3 H 7) Y - (OH) 3-X-Y] n, is the most commonly used binder in polymer bonded explosives (PBXs). In the structure of cellulose ester, hydroxyl groups are co-esterified with acetic acid and butyric acid [ 1 ].
  • Are cellulose acetate butyrate nanobiocomposites antimicrobial?
  • Effect of antimicrobial activity of cellulose acetate butyrate (CAB) nanobiocomposites against Escherichia coli O157:H7, Listeria innocua, Staphylococcus aureus and Saccharomyces cerevisiae.
  • Can cellulose acetate be used as a plasticizer?
  • Due to their high glass transition temperature, cellulose acetate-based systems are processed when blended with plasticizers. It is thus of utmost importance to study the miscibility and plasticizing effects of various molecules. We prepared CDA films via solvent casting method with diethyl phthalate as the plasticizer.
  • Who makes cellulose acetate butyrate?
  • Cellulose acetate butyrate with acetyl and butyryl contents of 29.5 and 17 wt%, respectively, was supplied by Sigma-Aldrich (Santiago, Chile). Organically modified MMT C30B purchased from Southern Clay Products Inc. (Gonzalez, TX, USA) contained methyl tallow bis-2-hydroxyethyl quaternary ammonium as an organic modifier.
  • How was cellulose acetate butyrate powder mixed?
  • Cellulose acetate butyrate powder, C30B, AM compounds and TEC were mixed in a laboratory-scale mechanical mixer (Waring 7011HS, Torrington, CT, USA) for 20 min and stored in sealed polypropylene.
  • Is secondary cellulose acetate plasticized by diethyl phthalate miscible?
  • We study the miscibility and dynamical properties of secondary cellulose acetate plasticized by diethyl phthalate (DEP). Partial miscibility (characterized by differential scanning calorimetry) is observed above 25 wt% of DEP content. The α-relaxation of the system and its VFT/WLF behavior are studied over a broad frequency range.
