Title:
FLUORINE-CONTAINING POLYMER PARTICLES AND DISPERSION LIQUID INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2021/200646
Kind Code:
A1
Abstract:
Provided are: fluorine-containing polymer particles that, by being mixed in a small amount with other particles, are capable of forming a coating film having excellent flexibility and chemical resistance; and a dispersion liquid that includes the same. Particles formed from a copolymer containing more than 20 mass% of a structural unit (X) derived from a fluorine-containing (meth)acrylate monomer (A), at least 30 mass% of a structural unit (Y) of a (meth)acrylate monomer (B), and more than 7 mass% to 30 mass% of a crosslinking agent (D), the particles being characterized in that the structural unit derived from the fluorine-containing (meth)acrylate monomer (A) is represented by general formula (1) and the structural unit derived from the (meth)acrylate monomer (B) is represented by general formula (2). (In formulas (1) and (2), R1 is hydrogen or a methyl group, R2 is a fluorine-containing hydrocarbon group having 1-10 carbon atoms, R3 is a group selected from the group consisting of benzyl groups and cyclic hydrocarbon groups having 5-10 carbon atoms, and a and b represent the degree of polymerization.)
