Beschreibung
Zusammenfassung:	The invention relates to a polymer with ethylenic unsaturations incorporating silylmetallocene groups, a process for the manufacture of these polymers and a propellant composition having the polymer of the invention as a binder. The polymer of the invention incorporates ethylenic unsaturations, to at least some of which there are added silylmetallocene groups of formula in which M denotes a transistion metal such as, for example, iron, the radicals R1, R2 and R3 being hydrocarbon 2 radicals. The polymer may be a hydroxytelechelic or carboxytelechelic polybutadiene. This modified polymer is employed as a binder in composite propellant compositions, thus making it possible to solve the problem related to the migration of the combustion catalyst. The invention has application particularly in the field of solid propulsion.
