Claims20
An article comprising a molded component configured to receive a terpene containing oil composition, said molded component formed of a copolyester composition comprising at least one copolyester that comprises:
- (a) a dicarboxylic acid component comprising:
- i) 70 to 100 mole % of terephthalic acid residues;
- (b) a glycol component comprising:
- i) 5 to 15 mole % of 2,2,4,4-tetramethyl-1,3-cyclobutanediol residues;
- and
- ii) 85 to 95 mole % of 1,4-cyclohexanedimethanol residues,
- 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 is 0.60 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 the polyester has a Tg of 95° C. to 115° C.
