Abstract: A polyester polymer and a method for manufacturing the same are revealed. Sulfonate groups (—SO3) are used for modification of polyethylene terephthalate (PET) and chemical extrusion technique is used in modification processes. The physiochemical properties of PET sulfonate obtained including moisture absorption, secondary transition temperature, melting point etc. are improved significantly. Thus the dyeing process can be carried out at lower temperature and the dyeing depth is improved. The purpose of energy saving and reduced carbon dioxide emission are further achieved.
