  1. Case study objectives.Two routes to SRP Solid rocket propellant (SRP) references G. P. Sutton and O. Biblarz, Rocket Propulsion Elements, 8th Ed., John Wiley, 2010. J.-J. Jutier, A. de Gunzbourg and R. E. Prud’homme, Synthesis and characterization of poly(3,3-bis(azidomethyl)oxetane-co-e-caprolactone)s, J. Polym. Sci.: Part A: Polymer Chemistry, 37, 1027-1039 (1999).

  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
