The invention relates to a method for producing a polyester which contains a) a furan dicarboxylic acid component (A) which comprises at least one dialkyl ester of a furan dicarboxylic acid, b) a dicarboxylic acid component (B) which comprises at least one aliphatic dicarboxyl acid or the dialkyl ester or anhydride thereof, c) an alcohol component (C) which comprises at least 1,4-butanediol, and d) a catalyst (D), wherein all of the components of the reaction mixture are reacted together; and polyester containing a) a furan dicarboxylic acid component (A) which comprises at least one furan dicarboxylic acid, b) a dicarboxylic acid component (B) which comprises at least one dicarboxylic acid, and c) an alcohol component (C) which comprises at least 1,4-butanediol, the hydroxyl number being > 0 to 50 mg KOH/g and the acid number being 0 to 2.5 mg KOH/g. The invention also relates to the use of the polyesters according to the invention in order to produce films, packaging, containers, foamed products, fibers, or composite materials.
