Study on Cellulose Acetate Butyrate/Plasticizer Systems by
Cellulose acetate butyrate (CAB) is a widely used binder in polymer bonded explosives (PBXs). However, the mechanical properties of PBXs bonded with CAB are usually very poor, which makes the charge edges prone to crack.
Study on Cellulose Acetate Butyrate/Plasticizer Systems by
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 ].

Sustainable PHBV/Cellulose Acetate Blends: Effect of a Chain
Abstract. Poly (3-hydroxybutyrate- co -3-hydroxyvalerate) (PHBV) and cellulose acetate (CA) were blended in the presence of a plasticizer, i.e., triethyl citrate (TEC), and a chain extender, i.e., poly (styrene-acrylic- co -glycidyl methacrylate). To increase the ductility and impact properties of PHBV and to investigate a new biodegradable
Mechanical and ultimate properties of injection molded
Mechanical and optical properties of plasticized cellulose acetate have been studied by ( Ishikawa & Tadano, 1987) on samples obtained via solvent casting. The stress-strain relation of cellulose acetate was studied by uniaxial tension test under various strain rates and temperature.
- What is cellulose acetate butyrate (CAB)?
- 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 .
- What are the dynamic properties of plasticized cellulose acetate?
- Dynamic Properties of Plasticized Cellulose Acetate 138 If the molecular origin of the E-relaxation is the localized motion of cellulosic chain, then the nature of the molecular origin of the E-relaxation is actually the same as the D-relaxation.
- How does plasticizer interact with cellulose acetate?
- It is also susceptible to interact with cellulose acetate in a different way due to the presence of the aromatic ring. Three plasticizer contents are selected to illustrate various miscibility behaviors: r 10% DEP, represents a totally miscible system.
- How to study miscibility of plasticized cellulose acetate?
- Miscibility study of plasticized cellulose acetate is also analyzed through small-angle neutron scattering technique. Phase separation, cavities partially filled with plasticizers and concentration fluctuations are found when performing neutron experiments.
- Do plasticized cellulose acetates have a relaxation behavior as a function of temperature?
- This Ph.D. thesis work is focused on the study of plasticized cellulose acetate and their relaxation behavior as a function of temperature. 3 degrees of substitution (DS) plasticized by triacetin (TA) or diethyl phthalate (DEP) have been analyzed, discussed and compared. TA-plasticized cellulose acetates share similar behaviors.
- Why does cellulose acetate have a regular periodicity?
- This observation is supposed to be related to the fact that more and more plasticizer molecules enter into cellulose acetate’s system with increasing plasticizer content. Their presence can create disorder of the polymer chains and thus mask the regular periodicity of cellulose acetate.
