Process for producing fluoropolymer |
摘要 |
The present invention has for its object to provide a method of producing fluoropolymers with high productivity under comparatively low temperature and low pressure conditions which are conducive to reduced cost of commercial-scale production equipment. The present invention is directed to a method of producing a fluoropolymer which comprises polymerizing a radical polymerizable monomer in a defined reaction-field, said radical polymerizable monomer comprising a fluorine-containing ethylenic monomer and said defined reaction-field being in supercriticality-expression state with a monomer density [rho<SUB>m</SUB>]-monomer critical density [rho<SUB>0</SUB>] ratio of [rho<SUB>m</SUB>/rho<SUB>0</SUB>] not less than 1.1.
