Zusammenfassung:	The present invention relates to quaternized bis(2-hydroxyethyl) terephthalate, and a preparation method therefor and the use thereof. The preparation method for quaternized bis(2-hydroxyethyl) terephthalate comprises: firstly using a protonic acid and a Lewis acid for concerted catalysis, subjecting bis(2-hydroxyethyl) terephthalate to monochloromethylation using paraformaldehyde so as to obtain a monochloromethylation product, and subjecting the monochloromethylation product to quaternization so as to obtain quaternized bis(2-hydroxyethyl) terephthalate. The use thereof is to subject the quaternized bis(2-hydroxyethyl) terephthalate to condensation polymerization so as to prepare quaternized and modified cationic polyethylene terephthalate. The method of the present invention can realize simple preparation; the product of the present invention has a high monochloromethylation yield; and the modified polyester obtained from the use of the present invention has good antibacterial, antistatic and dyeing proper
