Document Type and Number:
WIPO Patent Application WO/2023/127617
Kind Code:
A1
Abstract:
The present invention provides a technology for improving the dispersibility of fluororesin in various solvents. This dispersant for fluororesin comprises a copolymer. The copolymer includes a copolymer obtained by polymerizing a constituent monomer (a) that contains a (meth)acrylate compound (a1) represented by Rf-Cb-R-O-X, and a (meth)acrylate compound (a2) represented by HO-(PO)p-Y, wherein Rf is a perfluoro (poly)ether group, Cb is one linking group selected from the group consisting of an ester bond, an amide bond, and a urethane bond, R is an alkylene group having 1 to 8 carbon atoms, X and Y are acryloyl groups or methacryloyl groups, PO is an oxypropylene group, and p is a number of 2 to 150.
