| titleOfInvention | Certain polyester compositions which comprise tetramethylcyclobutanediol, cyclohexanedimethanol and high trans- cyclohexanedicarboxylic acid |
| abstract | Described as one aspect of the invention are polyester compositions A polyester composition comprising at least one polyester which comprises: (A) a dicarboxylic acid component comprising: i) 70 to 100 mole % of cyclohexanedicarboxylic acid residues or an ester thereof comprising: (a) 80 to 99 mole % /rans-cyclohexanedicarboxylic acid residues or an ester thereof; and (b) 1 to 20 mole % c/s-cyclohexanedicarboxylic acid residues or an ester thereof; ii) O to 30 mole % of aliphatic dicarbQxidjc acid residues, other than cyclohexanedicarboxylic acid residues, having up to 16 carbon atoms or esters thereof, other than cyclohexanedicarboxylic acid residues,; and iii) O to 10 mole % of aromatic dicarboxylic acid residues having up to 20 carbon atoms; and (B) a glycol component comprising: i) 5 to 35 mole % of 2, 2, 4, 4-tetramethyl-1, 3-cyclobutanediol residues; and ii) 65 to 95 mole % of 1, 4-cyclohexanedimethanol residues, 1, 3-cyclohexanedimethanol residues, 1, 2-cyclohexanedimethanol residues or esters thereof or mixtures thereof, wherein the total mole % of said dicarboxylic acid component is equal to 100 mole %; the total mole % of said glycol component is equal to 100 mole %; wherein the inherent viscosity of said polyester is from 0.35 to 1.2 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 said polyester has a Tg of from 66 to 120°C. The polyesters may be manufactured into articles. |
