METHOD FOR MAKING FLUOROPOLYMERS

The invention pertains to a method of making fluoropolymer dispersions using certain polyfunctional perfluoropolyether derivatives including a plurality of ionisable groups selected from the group consisting of -SO.sub.3X.sub.a, -PO.sub.3X.sub.a and -COOX.sub.a, whereas X.sub.a is H, an ammonium gro...

More Information
Summary:The invention pertains to a method of making fluoropolymer dispersions using certain polyfunctional perfluoropolyether derivatives including a plurality of ionisable groups selected from the group consisting of -SO.sub.3X.sub.a, -PO.sub.3X.sub.a and -COOX.sub.a, whereas X.sub.a is H, an ammonium group or a monovalent metal, and whereas said groups are comprised as pendant groups in the perfluoropolyether chain, and to fluoropolymer dispersions therefrom.
