Abstract

Extrusion blow molded (EBM) articles comprising a polyester having a dicarboxylic acid component and a glycol component. The dicarboxylic acid component comprises at least 90 mole % terephthalic acid residues. The glycol component comprises at least 75 mole % ethylene glycol residues and 15 to 25 mole % residues of a difunctional glycol such as, for example, 1,4-cyclohexanedimethanol. Such EBM articles can exhibit reduced haze, reduced sharkskin, and/or increased compatibility in PET recycling.
