摘　　要：本文比较了几种有代表性的双核二茂铁衍生物与单核二茂铁衍生物的挥发迁移性能与迁移对燃速的影响.结果表明迁移较之挥发是一种主要的影响.双核二茂铁衍生物比单核的迁移慢,在包复层中的共容增塑量低,但它迁移至包复层中的实际铁含量比单核的高.当推进剂中铁含量相同时,双核二茂铁衍生物的燃速催化效能比单核的高.从迁移性能与燃速催化效能来看,双核二茂铁衍生物中以DPFB为好.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.
