摘要：
Emulsifier free fluoropolymer manufacturing method in which (a) a mixture of an oxidizing agent and reducing agent is used to start the polymerization and where one or the other but not both, are further added during polymerization, or (b) an oxidizing metal ion is added to start polymerization and where additional oxidizing metal ion is added during polymerization.
