英文摘要A primary study on the synthesis of polylactone- grafted polyphosphazene copolymers has been carried out for the purpose of using them as cell scaffold material in tissue engineering. It was found that the copolymer could be obtained via transesterification of hydroxyl-ended polylactone, such as polycaprolactone (PCL) and polylactide (PLA), with poly [bis( glycine ethyl ester) phosphazene ] (PGP). However, it was needed to note that this process seemed more suitable for the preparation of PCL-grafted polyphosphazene copolymer than for other polylactone-grafted polyphosphazene copolymers, because the melting point of PCL (ca. 60 degrees C) was far below the reaction temperature (160 degrees C) which facilitated the mixing of the two polymers. Moreover, the transesterification of PCL with PGP could proceed satisfactorily only if the molecular weight of PCL was less than 8000,which was considered due to the weakened reactivity of hydroxyl end groups with molecular weight increase. Further detailed study is underway to optimize the reaction and it will be focused on the thermostability of poly[(amino acid alkyl ester) phosphazenes] influencing the transesterification.
