Patent ID: 8604139

Claim:
An extrusion profile article comprising at least one polyester which comprises: (a) a dicarboxylic acid component comprising: (i) about 90 to about 100 mole % of terephthalic acid residues; (ii) about 0 to about 10 mole % of aromatic and/or aliphatic dicarboxylic acid residues having up to 20 carbon atoms; and (b) a glycol component comprising: (i) 77 to about 85 mole % ethylene glycol residues; and (ii) about 15 to 23 mole % residues of 1,4-cyclohexanedimethanol; and (iii) about 2 mole % or less of diethylene glycol; (c) at least one branching agent in the amount of 0.01 to 1.0 mole %; wherein the total mole % of the dicarboxylic acid component is 100 mole %, and wherein the total mole % of the glycol component is 100 mole %; and wherein the inherent viscosity of the polyester is from 0.50 to less than 0.75 dL/g as determined in 60/40 (wt/wt) phenol/tetrachloroethane at a concentration of 0.25 g/50 ml at 25° C.; and having a haze value of less than 5% at shear rates greater than 500 sec −1 as measured by ASTM D1003, Method A.
