Insensitive munitions and combustion characteristics of BAMO/NMMO propellants
Journal of Energetic Materials, 1996Abstract Burning characteristics and sensitivities to the ballistic shock were investigated for BAMO/NMMO composite propellants oxidized with HMX, AP, and AN. Tests of card gap, fragment impact (FI), electrostatic discharge (ESD), and bullet impact were conducted to evaluate their sensitivities.

Viscosity‐molecular weight relationship for cellulose solutions in either NMMO monohydrate or cuen
Journal of Applied Polymer Science, 2010AbstractThe intrinsic viscosities, [η], of nine cellulose samples, with molar masses from 50 × 103 to 1 390 × 103 were determined in the solvents NMMO*H2O (N‐methyl morpholin N‐oxide hydrate) at 80°C and in cuen (copper II‐ethlenediamine) at 25°C. The evaluation of these results with respect to the Kuhn–Mark–Houwink relations shows that the data for ...

Preparation of the Reed Cellulose Membrane by Using NMMO Method
Advanced Materials Research, 2012The reed cellulose was extracted from the wild reed in the hot 12% sodium hydroxide (NaOH) aqueous solution. Then, the cellulose membrane was successfully prepared by using the reed cellulose as the raw materials dissolved in the solvent of N-methylmorpholine-N-oxide (NMMO).

Preparation of cellulose films from solution of bacterial cellulose in NMMO
Carbohydrate Polymers, 2012Bacterial cellulose (BC) was dissolved in N-methylmorpholine N-oxide (NMMO) to prepare regenerated BC films (RBC) with phase inversion. The solubility of BC, supermolecule on structure, morphology, thermal and physical properties of the films were investigated by Fourier transform infrared spectroscopy (FT-IR), solid-state cross polarization/magic ...

Combustion behavior of boron-based BAMO/NMMO fuel-rich solid propellants
Journal of Propulsion and Power, 1991Combustion characteristics of boron/poly(BA MO/NMMO) fuel-rich solid propellants have been studied due to their potential application to solid-fuel ramjets (SFRJ). For the same boron content, BAMO/NMMO copolymer-based fuels are superior to conventional hydroxyl terminated polybutadien (HTPB) fuels due to their vigorous pyrolysis characteristic for ...

Dynamic rheology behavior of electron beam-irradiated cellulose pulp/NMMO solution
Radiation Physics and Chemistry, 2008Abstract The rheological behavior of irradiated cellulose pulp solution by electron beam was investigated. Storage modulus G ′, loss modulus G ″, the dependence of complex viscosity η * and frequency ω of cellulose solutions were measured by DSR-200 Rheometer (Rheometrics co., USA).
