The effect of the concentration of disodium 1,2-dicarbomethoxyethylphosphonate as modifier in the trans-esterification stage of polyethyleneterephthalate preparation has been studied. It has been found that trans-esterification proceeds normally at modifier concentrations of up to 9°~ by weight, in
