| Abstract: |
| The crystallization of polyethylene glycol in the NEPE propellants was studied by means of X ray diffraction technique The influence of fillers, chemical crosslinking, and plasticizers on crystallization of polyethylene glycol was discussed The results indicated that several factors can decrease significantly the crystallinity of polyethylene glycol |
| Key words: Polyether propellant Propellant binder Polyethylene glycol X ray diffraction analysis,Crystallinity |
