Abstract: In this paper,volatility and migration of some represatative derivatives of gem-bis (ferrocenyl) alkane (DMFM, DEFP and DPFB) and mono- (ferrocenyl) alkane (TBF and AF)are compared with each other, and the effects of migration on the burning rate are discussed.It is shown that migration is more important factor to effect burning rate than volatility and the effects of their migrations follow the order. TBF>AF>gem-bis (ferrocenyl) alkane.The migration rate and the capacity of compatible plasticization of gem-bis(ferrocenyl)alkane are lower than that of mono-(ferrocenyl)alkane, however the iron of the former(GBA) migrated into the liner is more than that of the latter(MA). When iron content in the propellant is the same, the former is better than the latter with respect to the catalytical effect on burning rate.In view of the migration performance and the catalytical effect on burning rate, DPFB is the best one among GBA.
