Title:
POLYFLUOROALKYLPHOSPHONIC ACID OXYALKYLENE ESTER, METHOD FOR PRODUCING SAME AND RELEASE AGENT CONTAINING SAME AS ACTIVE INGREDIENT
Document Type and Number:
WIPO Patent Application WO/2011/030775
Kind Code:
A1
Abstract:
Disclosed is a polyfluoroalkylphosphonic acid oxyalkylene ester: CnF2n+1(CH2CF2)a(CF2CF2)b(CH2CH2)cP(O)[O(RO)mR']d(OH)2-d [wherein RO represents a linear or branched oxyalkylene group having 2 to 6 carbon atoms, R' represents a hydrogen atom, or an alkyl group or an aralkyl group having 1 to 20 carbon atoms, n represents 1 to 6, a represents 1 to 4, b represents 1 to 3, c represents 1 to 3, d represents 1 or 2, and m represents 1 to 100], which is a compound having a perfluoroalkyl group with 6 or less carbon atoms considered to have a low bioaccumulation potential, and exhibits releasing performance equivalent to that of a compound having a perfluoroalkyl group with 8 or more carbon atoms when being used as the active ingredient of a release agent. This compound is produced by subjecting a polyfluoroalkylphosphonic acid: CnF2n+1(CH2CF2)a(CF2CF2)b(CH2CH2)cP(O)(OH)2, and a polyalkylene glycol or a monoether thereof: HO(RO)mR' to a condensation reaction.
