Claim 0:
1. A polyester comprising:
from about 15 to about 40 weight percent monomer repeat units of isosorbide, based on the total weight of the polyester;
from about 25 to about 60 weight percent monomer repeat units of a dicarboxylic acid or anhydride, based on the total weight of the polyester; and
from about 10 to about 20 weight percent monomer repeat units of a polyhydric alcohol, based on the total weight of the polyester,
wherein the polyester has a weight average molecular weight of at least 8000 Daltons, as determined by ASTM D5296-05 and
wherein the dicarboxylic acid or anhydride comprises a mixture of (1) succinic acid or succinic anhydride and (2) nadic anhydride, methyl nadic anhydride, C36 dimer acid, or partially hydrogenated C36 dimer acid, and mixtures thereof.
