Polyester compositions which comprise tetramethyl cyclobutanediol and ethylene glycol, with improved catalyst system |
| abstract |
Described as one aspect of the invention are polyester compositions including at least one polyester which comprises:n (a) a dicarboxylic acid component comprising about 90 to about 100 mole % of terephthalic acid residues; and (b) a glycol component comprising:n (i) about 10 to about 27 mole % 2,2,4,4-tetramethyl-1,3-cyclobutanediol residues; and (ii) about 73 to about 90 mole % ethylene glycol residues; n wherein the total mole % of the dicarboxylic acid component is 100 mole %, and wherein the total mole % of the glycol component is 100 mole %; wherein the inherent viscosity of the polyester is from 0.50 to 0.8 dL/g; and wherein the L* color values for the polyester is 90 or greater. The polyesters may be manufactured into articles. |
