摘要：
Disclosed is a polyfluoroalkylphosphonic acid oxyalkylene ester of the formula: CnF2n+1(CH2CF2)a(CF2CF2)b(CH2CH2)cP(O)[O(RO)mR′]d(OH)2-d (RO is a C2-C6 linear or branched oxyalkylene group, R′ is a hydrogen atom or a C1-C20 alkyl group or aralkyl group, n is 1 to 6, a is 1 to 4, b is 1 to 3, c is 1 to 3, d is 1 or 2, and m is 1 to 100), which is a compound having a perfluoroalkyl group containing 6 or less carbon atoms and referred to as having low bioaccumulation potential, and exhibiting, when used as an active ingredient of a mold-releasing agent, mold release performance equivalent to that of a compound having a perfluoroalkyl group containing 8 or more carbon atoms. This compound is produced by subjecting a polyfluoroalkylphosphonic acid of the formula: CnF2n+1(CH2CF2)a(CF2CF2)b(CH2CH2)cP(O)(OH)2 and a polyalkyleneglycol or a monoether thereof of the formula: HO(RO)mR′ to a condensation reaction.
