WebFurthermore, because of the differently oriented anisotropies of neighbouring crystals, the material is also micro-inhomogeneous. Macroscopic anisotropy and micro-inhomogeneity are thus fundamental properties of all polycrystalline materials. Therefore, ... WebAbstract: Neutral polymer bonding agent (NPBA) is one of the most promising polymeric materials, widely used in nitrate ester plasticized polyether (NEPE) propellant as bonding agent. The structure and dynamics of NPBA under different conditions of temperatures and sample processing are comprehensively investigated by solid state NMR (SSNMR). The
