New polyesteramides having glass transition temperatures (Tg's) of up to 130 DEG C. and heat deflection temperatures that are in the 100 DEG C. to 110 DEG C. range are disclosed. The new polyesteramides of this invention are made by sequential addition of selected diamines to the diacid/glycol melt. The polyesteramides comprise: -[-A-G-]x-[-A-NH-R-NH-]y-wherein A is an organic dicarboxylic acid; G is a glycol selected from linear aliphatic diols and cycloaliphatic diols having 5 to 20 carbon atoms; R is selected from alkyl, cycloalkyl, arylkyl, or aryl; and x and y are whole numbers having an x/y ratio between about 9 to about 0.5 and sum of X and Y is from about 2 to about 500.
