Patent ID: 7704605

Claim:
A thermoplastic article produced by a polyester-containing composition comprising a polyester which comprises: (a) a dicarboxylic acid component comprising: i) from about 70 to 100 mole % of terephthalic acid residues; ii) 0 to about 30 mole % of an aromatic dicarboxylic acid residues having up to 20 carbon atoms; and iii) 0 to about 10 mole % of an aliphatic dicarboxylic acid residues having up to 16 carbon atoms; and (b) a glycol component comprising: i) about 30 to 40 mole % of 2,2,4,4-tetramethyl-1,3-cyclobutanediol residues; ii) about 60 to 70 mole % of 1,4-cyclohexanedimethanol residues, and iii) 0 to 10 mole % ethylene glycol; wherein the total mole % of the dicarboxylic acid component is 100 mole %, and the total mole % of the glycol component is 100 mole %; and wherein the inherent viscosity of the polyester is from about 0.50 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.; and wherein the polyester has a Tg of from about 110 to 130° C.; wherein said polyester-containing composition comprises no polycarbonate.
