摘要： A copolyester comprising a dicarboxylic acid component comprising (a) 80 to 99.5 mol % of terephthalic acid or an ester forming derivative thereof and (b) 0.5 to 4.5 mol % of a phenylenedioxy diacetic acid or an ester forming derivatives thereof and a diol component is described. Hollow containers and stretched film produced from the copolyester are further described. The copolyester has a high transparency, superior gas barrier property, mechanical strength, water resistance and heat resistance. In addition, since the copolyester has a low oligomer content, it scarcely contaminates a mold used in molding process, which leads to a high productivity. The molded article produced from the copolyester can be used widely as packaging materials including various films, sheets and containers. Moreover, since a molded article having superior properties is obtained form the copolyester alone, it is possible to manufacture various packaging materials without using a complicated apparatus and complicated process.
