ABSTRACT:
A copolyester composition which includes polyethylene terephthalate (PET) is used to manufacture bottle embryos having weight greater than 600 grams and thickness greater than 7.0 millimeters. The copolyester composition of this invention is used to manufacture containers having an inner volume greater than 10 liters. The components of this copolyester composition are polyethylene terephthalate resin, X mole % of isophthalic acid (IPA), Y mole % of diethylene glycol (DEG) and Z mole % of 2, 6 napthalene dicarboxylic acid where X, Y, and Z conform to the following conditions:2.5≦X<6.0,2.5≦Y≦5.0,0≦Z≦5.0; andthe copolyester composition has an intrinsic viscosity of between 0.75 and 0.85 dl/g.
