Improving the Mechanical Properties of Composite Rocket Propellants
, 2004 Solid composite rocket propellants usually contain ammoniumperchlorate embedded in an elastic polymer binder. The bindercan be based on a liquid prepolymer such as hydroxyl-terminatedpolybutadiene, HTPB, or poly(3-nitratomethyl-3-methyl oxetane,PolyNIMMO.

Hydroxy-terminated polyether binders for composite rocket propellants
, 2007 Propellants based on cross-linked Hydroxy Terminated PolyEther (HTPE) binders are being used as alternatives to Hydroxy Terminated PolyButadiene (HTPB) compositions. HTPE propellants have similar mechanical properties to HTPB propellants but they give a less severe response in ‘slow cook-off’ tests for IM compliance. A literature review is presented on
