A polymer mainly prepared with 6-aminohexanoic acid and another assistant five kinds of amino acids were synthesized in this study for evaluating the physicochemical characteristic

in vitro

and

in vivo

bioactivity as bone repair materials. The transforms infrared (FT-IR)、X-ray diffraction analysis (XRD)、differential scanning calorimetry(DSC) and thermal gravity analysis(TG) were investigated and characterized; The scanning electron microscopy (SEM) was tested for evaluating the

in vitro

bioactivity after soaking the polymer into simulated body fluid (SBF) with five days; The implantation of polymer into muscles and femur condyle of rabbits was assessed for evaluating the

in vivo

bioactivity of the polymer. The results showed that the polymer possessed amide band and was semi-crystallization structure

further the melting temperature and crystallization temperature was 205.9℃ and 159.5℃

respectively; The polymer could induce the form of apatite in the surface of polymer

showing good bioactivity; The implantation of polymer into muscles and femur condyle of rabbits results stated that the polymer had no visible inflammation and had contacted directly between implants and tissue without newly formed fibrous connective tissue. The fluorescence results showed that the polymer may possessed ectopic osteogenesis and have exactly great osteoconductivity

in vivo.
