| abstract |
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. |
