Abstract: The process involves… a) condensing aromatic dicarboxylic acids or esters thereof with at least one diol to give prepolymers having an acid number of from 2 to 8,… b) reacting the prepolymers with at least one molecular-weight-increasing compound, for example trimellitic anhydride, to give polyesters having acid numbers of from 40 to 60, and… c) dispersing the polyesters by adding aqueous mixtures of ammonia and amines in a molar ratio of from 10:1 to 1:10 to give a polyester melt which has a temperature in the range from 150 to 210 DEG C. … The polyester dispersions are used as sizes or sizing filament warp thread.
