COPOLYESTERS PLASTICIZED WITH POLYMERIC PLASTICIZER
Polyester-based films contain certain copolyesters (A) and polyester plasticizers (B). The copolyesters (A) may be selected from those in which the force required to stretch a film of the copolyester (A) by itself, from 2× to 5×, increases by less than 200%. The polyester plasticizers (B) have a wei...

| description | Polyester-based films contain certain copolyesters (A) and polyester plasticizers (B). The copolyesters (A) may be selected from those in which the force required to stretch a film of the copolyester (A) by itself, from 2× to 5×, increases by less than 200%. The polyester plasticizers (B) have a weight-average molecular weight of 900 to 12,000 g/mol, and contain (i) a diol component comprising residues of diols having 2 to 8 carbon atoms, and (ii) a diacid component comprising residues of dicarboxylic acids having 4 to 12 carbon atoms. These polyester-based films are particularly useful for preparing ultra-thin LCD or OLED polarizers, because they can be stretched very thin with a high stretch ratio at lower temperatures. |
