ABSTRACT:
The urethanes described are synthesized from aliphatic fluoro alcohols, triisocyanate and a carboxylic acid. They are prepared by reaction of the aliphatic fluoro alcohol with the triisocyanate to give the fluoro alcohol/triisocyanate adduct and by reaction of this adduct with the carboxylic acid. The new urethanes are preferably used for the finishing of textiles for the purpose of achieving water, oil and soil repellency.
