摘要 |
Disclosed are terpolymers having improved barrier properties and tensile strength relative to PET comprising copolyesters derived from acid components comprising about 45 to about 85 mol % terephthalic acid; about 10 to about 40 mol % of at least one naphthalenedicarboxylic acid and about 5 to about 15 mol % 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. |
