Abstract
A process for preparing allophane acid derivatives, characterized in that the alofanyl chloride is reacted with a substituted aryl or bisphenolic compound, containing at least one free hydroxyl group in which the substituents can be -OH, alkyl or aryl groups, proceeding in an anhydrous inert medium, chosen from aliphatic, cycloaliphatic or aromatic hydrocarbons.
