ABSTRACT:
Non-fluorinated tertiary aminic compounds, comprising two or more functional groups containing at least three active H, of the hydroxyl or aminic or thiol type, are utilized, in the form of a homogeneous mixture with perfluoropolyethers having hydroxy end groups, to prepare by means of polycondensation and cross-linking reaction with fluorinated or non-fluorinated polyisocyanates, carried out in the absence of catalysts, the corresponding polymers containing the perfluoropolyethereal chain deriving from the perfluoropolyether having hydroxy end groups.
