## Abstract Regularly alternating polyesteramides with glycol components ranging from C~2~ to C~14~ and interamide linkages ranging from 2 to 6 have been prepared by highβtemperature polycondensation of performed bisesteramides with sodium hydrogen tetrabutyltitanate as catalyst.
Hyperbranched polyesteramides (HB 1 and HB 2 ) were prepared by the bulk reaction between phthalic anhydride (PhAn) with either diisopropanolamine (DiPA) or diethanolamine (DEA), respectively. The hyperbranched polyesteramides were characterized by IR, GPC, 1 H-NMR, and thermal analysis (TGA and DSC
