일반식 [C3F7O{CF(CF3)CF2O}nCF(CF3)CH2O]2PO(OH) (여기에서, n은 1∼20의 정수임)로 표시되는 퍼플루오로폴리에테르인산에스테르. 이 화합물은 일반식 C3F7O{CF(CF3)CF2O}nCF(CF3)CH2OH 로 표시되는 퍼플루오로폴리에테르알코올을 옥시염화인과 반응시켜, 얻어진 일반식 [C3F7O{CF(CF3)CF2O}nCF(CF3)CH2O]2POCl 로 표시되는 화합물을 가수분해함으로써 제조된다. 또한 이 퍼플루오로폴리에테르인산에스테르 또는 그 염은 그것을 유효성분으로 하는 표면처리제를 형성시킨다. A perfluoropolyether phosphate ester represented by the general formula:        [C3F7O{CF(CF3)CF2O}nCF(CF3)CH2O]2PO(OH)(wherein n is an integer of 1 to 20). This compound is obtained by reacting a perfluoropolyether alcohol represented by the general formula:        C3F7O{CF(CF3)CF2O}nCF(CF3)CH2OH(wherein n is an integer of 1 to 20) with phosphorus oxychloride, and hydrolyzing the obtained compound represented by the general formula:        [C3F7O{CF(CF3)CF2O}nCF(CF3)CH2O]2POCl(wherein n is an integer of 1 to 20). Moreover, the perfluoropolyether phosphate ester or a salt thereof forms a surface treatment agent comprising the perfluoropolyether phosphate ester or a salt thereof as an active ingredient.
