Abstract

Processes for the recovery of a sulfopolyester polymer from an aqueous dispersion and a sulfopolyester concentrate are provided. Particularly, a sulfopolyester concentrate, from which the 'sulfopolyester may be recovered and reused, are formed by processes such as evaporation and/or nanofiltration. Final recovery of the sulfopolyester may be achieved by further evaporation of water and/or salt precipitation. In addition, the recovered sulfopolyester and articles manufactured from the recovered sulfopolyester are also provided.
