Tractable polyfluoral

Abstract

Abstract Low‐temperature polymerizations of fluoral with the use of ionic initiators in inert diluents have produced high molecular weight polyfluoral which is amorphous and tractable. The polymer can be end‐capped by standard techniques to give material which is thermally stable to 350–400°C. The stabilized polymer can be fabricated from solution or melt‐pressed at temperatures as low as 125°C to give clear films and coatings which are oil‐and water‐repellent but highly permeable toward oxygen and water vapor.
