Abstract
Methods of making a polymer having main chain 1,1,1,3,3,3-hexafluoroisopropylidene (6F) linkages are described herein. The method can include contacting hexafluoroacetone hydrate and a first aromatic monomer in the presence of an acid to provide the polymer, wherein the first aromatic monomer has a structure as defined herein. Polymers having main chain 1,1,1,3,3,3-hexafluoroisopropylidene (6F) linkages are also disclosed.
