“…Hydrogen bonding may dominate the intermolecular interactions due to the electron donor–acceptor interactions between the hydroxyl group of anisole or benzyl alcohol and the π-electrons of PEGOPE. For comparison purpose, the results of PEGOPE + 1-octanol show the volume expansion in the PEGOPE-rich region due to the dominant physical interactions and the volume contraction in the 1-octanol-rich region due to the dominant specific (chemical) interactions.…”

“…The results of such studies are definitely helpful in getting insight into the intermolecular interactions between polymeric glycol ethers and high polarity solvents, such as ethers and alcohols. Our research group measured the PVT properties of oligomeric poly(ethylene glycol) mono-4-octylphenyl ether (PEGOPE) + 1-octanol or acetophenone and oligomeric blends of poly(ethylene glycol) mono-laurate (PEGML) with PEGOPE at pressures from 0.1 to 50 MPa.…”

Densities were determined experimentally for the binary mixtures of poly(ethylene glycol mono-4-octylphenyl ether) (PEGOPE) + anisole or benzyl alcohol at 298.15−348.15 K and pressures from 0.1 to 50 MPa. All of the excess volumes are negative over the whole experimental conditions, indicating that the hydrogen-bonding effect is dominant in these two binary systems. Those isothermal and isobaric excess volumes correlate well with the Redlich−Kister equation. The specific volumes of the pure components and their mixtures were correlated with the Schotte and Flory−Orwoll−Vrij (FOV) equations of state to average absolute relative deviations (AARDs) no greater than 0.03%.

“…The molding quality cannot be predicted and controlled until the PVT relation of the material is obtained accurately. The correlation of PVT may be further applied to calculate various thermodynamic properties of the mixtures at the conditions of interest for engineering applications and even provide useful supporting evidence to reveal the molecular interactions between the constituent components [23]. Wang et al [25] studied the influence of measurement processes on pressure-specific volume-temperature relationships of polypropylene based on the isobaric cooling/heating processes and the isothermal compression/decompression processes.…”

“…Obviously, the above methods and simplifications cannot effectively track the molding process in single screw extrusion. Pressure-Volume-Temperature (PVT) properties are the essential properties of material and play significant roles in polymer molding [23,24]. As for the single screw extrusion, PVT is one of the most important rheological properties, which is closely related to the density, viscosity, pressure distribution, and even the molding quality [15].…”

Much of surplus ammunition stockpile inevitably requires demilitarized processing technology in the explosives industry. For the safe waste treatment and recycle, the thermoplastic polymer bonded explosive (PBX) can effectively reduce the military cost and non-conforming products. In addition, the thermoplastic PBX has excellent application prospect as the future explosive due to the good mechanical properties and insensitivity. However, for high solid content, most of thermoplastic PBXs still maintain a considerable viscosity even in high-temperature melting state, rendering traditional casting process unsuitable. In this study, a measuring method was adopted to accurately obtain the correlation of Pressure-Volume-Temperature (PVT) for the simulative materials of thermoplastic PBX at first. The equations of state for PVT and viscosity model were then created, which are of great significance in single screw extrusion. An experiment system of single screw extrusion was designed to implement the molding process considering the poor liquidity problem of the ther-moplastic materials. Excellent molding stability (1 < 0.5 % variation) was achieved for the extrusion system. Moreover, a numerical investigation was also performed. Good agreements were yielded by comparing the simulation data and experimental results. The effects of operational parameters, i. e., the entrance pressure, barrel temperature and rotation speed on molding process of the thermoplastic materials were investigated in detail. The wall shear stress decreases with the feed inlet well sealed whereas the maximum temperature rise increases a little due to limited thermal diffusion. Either increasing temperature or decreasing rotation speed is beneficial to overall process safety. However, production cycle and attainable molding density also need to be considered at the same time. Furthermore, the process parameters should be optimized on the basis of the PVT and viscosity properties of material in practice. The investigations above can be a better guidance for the development and implementation of thermoplastic PBXs molding process.
