Patent ID: 7915376

Claim:
A container comprising at least one polyester composition comprising at least one polyester which comprises: (a) a dicarboxylic acid component comprising: i) 80 to 100 mole % of terephthalic acid residues; ii) 0 to 20 mole % of aromatic dicarboxylic acid residues having up to 20 carbon atoms; and iii) 0 to 10 mole % of aliphatic dicarboxylic acid residues having up to 16 carbon atoms; and (b) a glycol component comprising: i) 20 to 30 mole % of 2,2,4,4-tetramethyl-1,3-cyclobutanediol residues; and ii) 70 to 80 mole % of 1,4-cyclohexanedimethanol residues, wherein the total mole % of said dicarboxylic acid component is 100 mole %, and the total mole % of said glycol component is 100 mole %; wherein the inherent viscosity of said polyester is from 0.60 to 0.75 dL/g as determined in 60/40 (wt/wt) phenol/tetrachloroethane at a concentration of 0.5 g/100 ml at 25° C.; wherein said polyester has a Tg of from 100 to 130° C.; and wherein said container comprises no polycarbonate.
