Diterminally Amine-Modified Perfluoropolyether Compound and Preparation Thereof, and Liquid-Repelling Composition, Cured Product and Coated Substrate Containing the Same

Abstract

Diterminally amine-modified perfluoropolyether compounds of the general formula (wherein Rf is a perfluoropolyether group; each R1 is independently an unsubstituted divalent hydrocarbon group of 1 to 10 carbon atoms; R2, R3 and R4 are each independently substituted or unsubstituted monovalent hydrocarbon groups of 1 to 10 carbon atoms; each R5 is independently an unsubstituted divalent hydrocarbon group of 1 to 10 carbon atoms; each R6 is independently a hydrogen atom or a substituted or unsubstituted monovalent hydrocarbon group of 1 to 50 carbon atoms which may include at least one oxygen, nitrogen, sulfur or silicon atom; each occurrence of ‘m’ is independently 0, 1 or 2; and each occurrence of ‘n’ is independently an integer from 0 to 8) are provided. Such compounds have a good solubility in solvents and reactive resins.
