dieses Erfindungsgedankens wurde nun gefunden, daß die Brenngeschwindigkeit überraschenderweise weiterhin sehr stark gesteigert werden kann, wenn ein derartiger Treibsatz neben den Cyclopentadienyl-Eisen-Verbindungen als weiteren Abbrandbeschleuniger ein Siliconharz enthält.this inventive concept has now been found that the burning rate surprisingly can furthermore be increased very greatly if such a propellant is used in addition to the cyclopentadienyl iron compounds contains a silicone resin as a further combustion accelerator.
Als Cyclopentadienyl-Eisen-Verbindungen können wie im Hauptpatent das Ferrocen selbst oder seine Derivate, wie Ferrocenaldehyd, Monoacetylferrocen, Phenylferrocen, Ferrocencarbonsäurenitril, Ferrocenylamin u. dgl., verwendet werden. Das erfindungsgemäß einzusetzende Siliconharz kann beispielsweise ein Alkylpolysiloxan (Molekulargewicht 1000 bis lOOOOO; Viskosität 50 bis 10 000 cSt), ein Phenylalkylpolysiloxan (Molekulargewicht 3000 bis 50000, Viskosität 300 bis 3000 cSt) od. dgl. sein.As cyclopentadienyl iron compounds, as in the main patent, ferrocene itself or its derivatives, such as ferrocene aldehyde, monoacetyl ferrocene, phenyl ferrocene, ferrocene carboxylic acid nitrile, Ferrocenylamine and the like can be used. The silicone resin to be used according to the invention For example, an alkylpolysiloxane (molecular weight 1000 to 10000; viscosity 50 to 10,000 cSt), a phenylalkylpolysiloxane (molecular weight 3,000 to 50,000, viscosity 300 to 3000 cSt) or the like.
