| titleOfInvention | Reactor Grade Copolyester for Shrink Films |
| abstract | Reactor grade copolyester compositions, as well as heat shrinkable films made therefrom, have unexpectedly higher ductility than multicomponent blends of copolyesters having the same monomer content. The reactor grade copolyester composition comprises at least about 90 mole percent diacid component, and (a) about 72 to about 88 mole percent ethylene glycol, about 10 to about 15 mole percent 1,4-cyclohexanedimethanol and about 2 to about 13 mole percent diethylene glycol, or (b) about 59 to about 77.5 mole percent ethylene glycol, about 15 to about 28 mole percent 1,4-cyclohexanedimethanol and about 7.5 to about 13 mole percent It is prepared from the diol component of diethylene glycol. In addition, heat shrinkable films can be made to closely match the shrinkage properties of polyvinyl chloride by varying the amount of diol component of the reactor grade copolyester composition. In addition, the reactor grade copolyester composition has a b * color value of -1.0 to less than 4.5, wherein the diacid component is at least about 90 mole percent terephthalic acid and the diol component is from about 52 to about 88 mole percent ethylene glycol, about 10 To about 28 mole% 1,4-cyclohexanedimethanol and about 2 to about 20 mole% diethylene glycol. |
