Optical media comprising polyester compositions formed from 2,2,4,4,-tetramethyl-1,3-cyclobutanediol and 1,4-cyclohexanedimethanol

摘要

Described are optical media comprising polyester compositions comprising polyesters which comprise (a) a dicarboxylicacidcomponent having terephthalic acid residues; optionally, aromatic dicarboxylic acid residues or aliphatic dicarboxylic acid residues or ester residues thereof; 2,2,4,4-tetramethyl-1,3-cyclobutanediol residues; and 1,4-cyclohexanedimethanol residues.
