摘要

Abstract

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（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 SEM micrographs that the amphiphilic polymer in water solution exhibited nano-spherical particles dispersion with 50～100 nm diameter.
