摘要
Abstract
The second generation of ferrocenyl-terminated polyamidoamine dendrimer (G2-PAMAM-Fc) has been successfully obtained by a reductive ammonification reaction between ferrocene formaldehyde and the third generation of hyperbranched polyamidoamine (G2-PAMAM). The thermal properties and the glass transition temperature have been investigated by thermal gravimetry (TG)-derivative thermal gravimetry (DTG), differential scanning calorimetry (DSC) techniques. The maximum graft degree of ferrocene on PAMAM is 78％ according to UV/visible spectra determined spectrophotometrically at 438 nm.The glass transition temperature of G2 PAMAM-Fc is higher than that of G2 PAMAM. PAMAM- Fc is more thermally stable than G2-PAMAM. The incorporation of ferrocene into dendrimer could efficiently improve its thermal stability. The probable mechanism of thermal stability is discussed.关键词
