## Abstract

This invention provides 1) novel reactive fluorinated compounds derived from a specified class of telomers or cotelomers of fluoroolefins; and 2) stable products and stable polymers thereof obtained by reaction or polycondensation of the novel reactive fluorinated compounds with specified classes of hydrogenated aliphatic, alicyclic, aromatic reactive compounds, telechelic oligomers and block polymers wherein said stable products and polymers contain hetero atoms such as oxygen, sulfur or nitrogen and are characterized by high thermal and chemical resistance.
