Abstract:

A kind of novel hybrid material was prepared by crosslinking poly[(glycino ethyl ester)0.6(alanino ethyl ester)1.2(chororide)0.2phosphazene](PAGP1) with amylose.The results show that the residual P—Cl groups in PAGP1 can be nucleophilic substituted by hydroxyl groups of amylose in the form of R—ONa. The obtained hybrid polymeric film exhibited no obvious phase separation, which commonly occurred in polymer blends. The crosslinked hybrid material had better mechanical properties than the blended PAGP2/amylose with similar composition, and was more hydrophilic than pure PAGP2. This novel material would be a good candidate to be applied for drug-controlled release and tissue engineering applications.
