Abstract
An aromatic polyester composition which comprises 5 to 95 wt % of an ethylene naphthalenedicarboxylate copolymer and 95 to 5 wt % of an ethylene terephthalate (co)polymer and has a compatibility between these polymers of 0.15 to 0.5, and whose melting point lowers depending on the content of ethylene naphthalenedicarboxylate. This composition has excellent compatibility, transparency, barrier properties and heat resistance and is an excellent raw material for forming various molded products, particularly bottles. A bottle and its production process are also disclosed.
