Abstract
Use of amorphous perfluoropolymers based on homopolymers of the TTD dioxole or its amorphous copolymers to prepare solutions in fluoro-containing solvents, to obtain solutions for coatings, wherein TTD has the formula: ##STR1## wherein R.sub.F is a perfluoroalkylic radical with 1-5 carbon atoms, linear or branched when possible; X.sub.1 and X.sub.2 equal to or different from each other being F or CF.sub.3 ; the TTD amount ranges from 40 to 100% by moles.
