ABSTRACT:
Urethanes made from aliphatic fluorinated alochols, isocyanates and substituted aromatic compounds, a process for their preparation, and their use.
The novel urethanes are synthesized from an aliphatic fluorinated alcohol, an isocyanate and a specific substituted phenol or aniline compound. They are prepared by reacting an aliphatic fluorinated alcohol with a di- or triisocyanate to form a fluorinated alcohol/isocyanate adduct and reacting this adduct with a certain substituted phenol or aniline to form the urethanes intended. The novel urethanes are preferably used for oleophobic and hydrophobic finishing of textiles and leather.
