| description | The invention discloses novel modified polyester as well as a preparation method and application thereof. The novel modified polyester comprises the following structural units derived from the following monomers in molar percentage: 5-50 mol% of aromatic diether diacid, 5-50 mol% of aromatic diester diacid, 5-50 mol% of aromatic diester diacid, 5-50 mol% of aromatic diester 0 to 45 mol% of binary acid; and 50 mol% of dihydric alcohol. The aromatic diether diacid and the binary acid with specific structures are selected and copolymerized with the dihydric alcohol to prepare the high-performance polyester with high flowability, impact resistance and heat resistance, and the polyester can be applied to the fields of plates, sheets or special profiles and the like; the method has important significance for filling up the supply gap of domestic high-performance polyester and meeting the powerful requirements of potential markets.
