Title:
AQUEOUS DISPERSION OF FLUORINATED COPOLYMER
Document Type and Number:
WIPO Patent Application WO/2014/208338
Kind Code:
A1
Abstract:
An aqueous dispersion of a fluorinated copolymer that contains, as copolymerization units, (A) a (meth)acrylate represented by the formula: [CH2=CHRCOO(NH)rR1NR2R3R4]+Y-, (B) a perfluoroalkylalkyl (meth)acrylate or a polyfluoroalkylalkyl (meth)acrylate each represented by the formula: CmF2m+1CpH2p(NR'SO2)qOCOCR=CH2 or a polyfluoroalkyl (meth)acrylate represented by the formula: CnF2n+1(CH2CF2)a(CF2CF2)b(CH2CH2)cOCOCR=CH2, (C) benzyl (meth)acrylate, (D) a non-fluorinated polymerizable monomer that is different from the component (A) or (C), and (E) a polymerizable monomer containing a crosslinkable group. When the aqueous dispersion is used as a water-repellent oil-repellent agent containing a fluorinated copolymer as an active ingredient, the dispersion stability of an aqueous water-repellent oil-repellent agent dispersion produced using the aqueous dispersion can be improved.
