Anionic copolyesters with sodium sulfonate functions and short polyethylene oxyde blocks are used for polyester filament sizing. These polymers were prepared using a three stages melting process at high temperature combining ester interchange, direct esterification, polycondensation and etherification reactions. A study on the relationship between chemical structure and physico‐chemical properties (glass transition temperature, solubility behaviour, hydrolytical and thermal stability) shows that the control of the ether bridges content is important.
