METHOD FOR PRODUCING FLUORINE-CONTAINING POLYMER AND COMPOSITION THEREOF
Document Type and Number:
Japanese Patent JP2021185236
Kind Code:
A
Abstract:
To provide a method for producing a fluorine-containing polymer and a composition thereof.SOLUTION: There is provided a composition comprising a fluorine-containing polymer (A) containing a constituent unit having a fluorine-containing aliphatic ring as a main component and an aprotic solvent (B), wherein the fluorine-containing aliphatic ring of the fluorine-containing polymer (A) has one, two or three etheric oxygen atoms as a ring-constituting atom and when the fluorine-containing aliphatic ring contains a plurality of the etheric oxygen atoms, the etheric oxygen atoms are not adjacent to each other and the content of the fluorine-containing polymer (A) to the mass of the composition is 20 mass% or more.SELECTED DRAWING: None
