Aqueous emulsion polymerization in the presence of ethers as chain transfer agents to produce fluoropolymers

   
   

The present invention provides a method of making a fluoropolymer comprising repeating units derived from one or more gaseous fluorinated monomers. The method comprises an aqueous emulsion polymerization of gaseous fluorinated monomers in the presence of an ether selected from the group consisting of dimethyl ether (DME), methyl tertiary butyl ether (MTBE) and mixtures thereof.

La actual invención proporciona un método de hacer un fluoropolymer que abarca repitiendo las unidades derivadas de unos o más monomers fluorados gaseosos. El método abarca una polimerización acuosa de la emulsión de monomers fluorados gaseosos en la presencia de un éter seleccionado del grupo que consiste en el éter dimethyl (DME), el éter butílico terciario metílico (MTBE) y mezclas de eso.
