Enantioselectivity, swelling and stability of 4-hydroxyprolinol containing acrylic polymer beads in the asymmetric reduction of ketones
Thvedt, Thor Håkon Krane; Kristensen, Tor Erik Holt; Sundby, Eirik; Hansen, Tore; Hoff, Bård Helge (2011)A new 4-hydroxy-α,α-diphenyl-l-prolinol containing polymethacrylate, prepared without chromatography by a large scale adaptable synthesis, has been evaluated as a catalyst in the asymmetric reduction of 1-arylethanones. ... -
Isocyanate-Free and Dual Curing of Smokeless Composite Rocket Propellants
Landsem, Eva; Jensen, Tomas Lunde; Kristensen, Tor Erik Holt; Hansen, Finn Knut; Benneche, Tore; Unneberg, Erik (2013)Traditional composite rocket propellants are cured by treatment of hydroxyl-terminated prepolymers with polyfunctional aliphatic isocyanates. For development of smokeless composite propellants containing nitramines and/or ... -
Mechanical Properties of Smokeless Composite Rocket Propellants Based on Prilled Ammonium Dinitramide
Landsem, Eva; Jensen, Tomas Lunde; Hansen, Finn Knut; Kristensen, Tor Erik Holt; Unneberg, Erik (2012)Ammonium dinitramide (ADN) is a high performance solid oxidizer of interest for use in high impulse and smokeless composite rocket propellant formulations. While rocket propellants based on ADN may be both efficient, clean ... -
Neutral Polymeric Bonding Agents (NPBA) and Their Use in Smokeless Composite Rocket Propellants Based on HMXGAP- BuNENA
Landsem, Eva; Jensen, Tomas Lunde; Hansen, Finn Knut; Unneberg, Erik; Kristensen, Tor Erik Holt (2012)Very few efficient bonding agents for use in solid rocket propellants with nitramine filler materials and energetic binder systems are currently available. In this work, we report the synthesis, detailed characterization, ...
