    Abstract: A method for preparing an aromatic sulfide or a salt thereof is provided. The method for preparing an aromatic sulfide or a salt thereof includes reacting a compound having a structure represented by Formula (I) to a compound having a structure represented by Formula (III) in the presence of a compound having a structure represented by Formula (II) to obtain a compound having a structure represented by Formula (IV) wherein R1 and R2 are independently C1-6 alkyl group, or C5-7 cycloalkyl group; R3 is independently C1-6 alkyl group, C5-7 cycloalkyl group, C1-6 haloalkyl group, or aryl group; R4 is independently H, or C1-6 alkyl group; Y is H, aryl group, or —X—R5; X is —O—, —NH—, —PH—, or —S—, or Y and an adjacent R4 are optionally combined with the carbon atoms to which they are attached, to form an aryl group; and R5 is H, C1-6 alkyl group, C5-7 cycloalkyl group, or aryl group; and Z− is R3SO3−.

    Abstract: A polyester film is provided. The polyester film is produced from a composition that includes the following monomers: terephthalic acid, ethylene glycol, and a branched monomer having a structure represented by formula (I), formula (II) or formula (III): , wherein X is independently hydroxyl, carboxyl or —COOR, and R is C1-6 alkyl. The molar ratio between terephthalic acid and ethylene glycol ranges is between about 50:50 and 30:70. The molar percentage of the branched monomer is from about 1 mol % to 3 mol %, based on the total mole of terephthalic acid and ethylene glycol.
