摘要:
The invention provides a fluoropolymer liquid composition comprising a fluoropolymer and a film-forming auxiliary, said fluoropolymer comprising acid/acid salt fluorovinyl ether units represented by the general formula (I): said film-forming auxiliary being an organic liquid which is compatible with water and has a boiling point higher than 100° C. but not higher than 300° C., said fluoropolymer liquid composition being a fluoropolymer dispersion composition comprising said film-forming auxiliary and a fluoropolymer fine particle comprising said fluoropolymer, said fluoropolymer fine particle containing, at the proportion of at least 25% by mass thereof, a spherical fluoropolymer fine particle, and said spherical fluoropolymer fine particle being substantially spherical.
