| 摘要 |
Disclosed are terpolymers having improved barrier properties and tensile strength relative to PET comprising copolyesters derived from acid components comprising 45 to 85 mol percent terephthalic acid; 10 to 40 mol percent of at least one naphthalenedicarboxylic acid and 5 to 15 mol percent of at least one aliphatic dicarboxylic acid having 1 to 6 carbon atoms and glycol component comprising ethylene glycol. The copolyesters of the present invention may be formed into a variety of articles such as blood tubes, serum vials, containers, films and sheeting. |
