Synthesis and characterization of new polyethers containing aliphatic and aromatic spirodilactam

Abstract:

Novel highly fluorinated polyethers were synthesized by reacting 1,3-bis(1,1,1,3,3,3hexafluoro-2-pentafluorophenylmethoxy-2-propyl)benzene (12F-FBE) with 1,6-diazaspiro[4,4]-nonane-2,7-dione (spirodilactam, SDL). New fluorinated polymers were characterized by NMR, DSC, TGA, viscosity, GPC, water contact angle, water absorption, dielectric constant and elemental analysis. These materials formed clear, colorless films by solvent casting, but only moderate thermal stability was achieved in air (ca. 400°C).
