Abstract
The object of the present invention is novel solid pyrotechnic compositions with a loaded and plasticized thermoplastic binder, which can be used notably as propellants with non-polluting combustion, as propellants with a high combustion rate or as compositions generating non-toxic gases for air-bags. The plasticizer for the binder comprises a polybutadiene having a number average molecular weight of between 1500 and 7500 and having, added to some of its ethylenic non-saturations, silylferrocene groups.
