METHOD OF PREPARING FLUOROPOLYMERS BY AQUEOUS EMULSION POLYMERIZATION |
摘要 |
Method of making fluoropolymers by emulsion polymerization of one or more fluorinated monomers in an aqueous phase in the presence of a fluorinated emulsifier, said method comprises adding a doping agent in a weight ratio with respect to the emulsifier of from about 1:2 to about 1:20, said doping agent has a melting point of equal or less than 30° C. and a boiling point of at least about 100° C. and is selected from the group consisting of fluorinated cyclic hydrocarbons, fluorinated polyoxyalkenes, fluorinated alkenes and fluorinated polyoxyalkenes. |
