Use of tertiary aminic compounds containing at least three active hydrogens in the preparation of polymers containing perfluoropolyethereal chains.

摘要

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.
