Abstract
Described are polymer compositions that include a blend of copolyester polymers based on monomers that include on terephthalic acid (TPA), isophthalic acid (IPA) and 1,4-cyclohexanedimethanol (CHDM), wherein the blend includes a first copolyester that is semi-crystalline and a second copolyester that is amorphous; and films made from the polymer compositions useful for transparent high temperature conductive film applications.
