Comparative Case Study on Two Routes to Synthesizing Solid Rocket Propellant

This study evaluates two methods for synthesizing solid rocket propellant (SRP) by focusing on key objectives such as polymerization mechanisms, phase equilibria challenges, molecular weight distribution modeling, product analysis, and performance evaluation. Emphasizing sustainable practices, the research tackles catalyst deactivation, polymer precipitation, and solvent treatment. Various rheological properties will be assessed to ensure optimal performance. The findings aim to enhance understanding of energetic thermoplastic elastomers and their applications in rocket propulsion technology.

  2. Polymerization – ionic mechanism, copolymer system, link to physical properties [chapter 4] Phase equilibria – catalyst deactivation, polymer precipitation, polymer washing, polymer swelling in various solvents [chapter 5] Molecular weight distribution – from kinetics; modeling MWD data [chapter 6] Product analysis – sustainable process evaluation [chapter 7] Product performance – rheological properties [chapter 8] Case study scope case study goals

  3. Develop recipe from literature Model: copolymerization; substitution reaction on polymer Polymerization/C4 case study goals

  4. Catalyst deactivation – prevent precipitation while stopping all active sites Polymer precipitation – which solvents will work, and how can we remove them? Solvent swelling – how do we treat waste streams? Phase equilibria/C5 case study goals

  5. What is the expect chain length? How do we model the molecular weight distribution (fitting models to data)? Molecular weight distribution/c6 case study goals

  6. What tests can we use for QA/QC? Sustainable process evaluations of the two synthesis routes Product characterization/c7 case study goals

  7. Rheology Reheating/reuse/recycle Product performance/c8 case study goals
