Aqueous polymerization of fluorinated monomers using polymerization agent comprising fluoropolyether acid or salt and hydrocarbon surfactant
Abstract
The invention claims a is used for the triggering agent and polymerizer of the polymerizing at least one fluorizating monomer in the water content medium formed by fluorine-containing polymer particles the method for water aqueous dispersion, the water aqueous dispersion at least about 10 weight percent polymer the solid content. The polymerizer is the poly ether acid or a salt and surface - active agent's thereof. The water content medium comprises less than about pure of the hydrogen carboxylic acid salt or fluorine-containing surface active agent. Preferably added to the polymeric reaction initial in the polymer crystal's under the condition without to implement the method.
