摘　　要：A hyperbranched poly(ester-amide)(HP) with hydroxyl end-groups was synthesized from diisopropanolamine (DIPA) cis-1,2-clyclohexane-dicarboxylic anhydride (HHPA) and pentaerythritol (PETL), and a kind of amphiphilic hyperbranched macromolecule was prepared with the hydroxyl end-groups modified by the addition of polyethylene glycol monomethyl ether(M_W550, MPEG550).The structure of the macromolecules was characterized with IR, DSC, GPC and SEM.The results indicated that the hyperbranched poly(ester-amide) had narrow molecular mass distribution with polydispersity 1.47, and glass transformation temperature (T_g) 36℃.It was shown by SEM micrographs that the amphiphilic polymer in water solution exhibited nano-spherical particles dispersion with 50～100 nm diameter.A hyperbranched poly（ester amide） （HP） with diisopropanolamine （DIPA） cis-1, 2 clyclohexane-dicarboxyli （PETL）, and a kind of amphiphilic hyperbranched macromol hydr c an oxyl hydri ecule was end-groups was synthesized from de （HHPA） and pentaerythritol prepared with the hydroxyl endgroups modified by the addition of polyethylene glycol monomethyl ether （Mw550, MPEG550）. The structure of the macromolecules was characterized with IR, DSC, GPC and SEM. The results indicated that the hyperbranched poly （ester-amide） had narrow molecular mass distribution with polydispersity 1.47, and glass transformation temperature （Tg） 36℃. It was shown by amphiphilic polymer in water solution exhibited nano-spherical particles dispersion with 50 - 100 nm diameter.
