Title: Recovery of fluorinated monomer
Inventor: WATAKABE ATSUSHI
IPC: C08F14/18
Filed: 1997-07-24
Abstract: PROBLEM TO BE SOLVED: To enable efficient recovery of unreacting fluorinated monomer by bringing a latex resulting from emulsion polymerization of fluorinated monomer into contact with a solvent that has little influence on the global warming without anxiety of depletion of the ozone layer. SOLUTION: The latex resulting from the emulsion polymerization of a fluorinated monomer having a boiling point of 20-300 deg.C, preferably a fluorinated functional monomer bearing a carboxylic acid type functional group or a sulfonic acid type functional group, is brought into contact with a hydrofluoro-ether thereby recovering unreacted fluorinated monomer. The hydrofluoro-ether has preferably of 4-12 carbon atoms, particularly C4 H9 OCH3 , C4H9OCH2 H3 or CF3 CF2 CF2 OCH3 . According to this process, the unreacted fluorinated monomer is efficiently recovered before coagulation and the reduction in the recovery yield can be avoided that is caused by degeneration of the latex on its coagulation.
