Abstract
The invention relates to a process for producing at least one alkoxylated polyphenol comprising the following successive steps: (a) reacting at least one polyphenol, at least one alkoxylating agent, at least one catalyst, in the presence of at least one alkoxylated polyphenol as a solvent, the polyphenol/polyphenol alkoxylated weight ratio as a solvent being less than 2, preferably less than or equal to 1.5, more preferably less than or equal to 1, even more preferably less than or equal to 0.5; and (b) removing the residual alkoxylating agent.

A process for producing at least one alkoxylated polyphenol comprising the following successive steps:
- (a) reacting at least one polyphenol, at least one alkoxylating agent and at least one catalyst in the presence of at least one alkoxylated polyphenol as a solvent,
- wherein the (polyphenol)/(alkoxylated polyphenol as a solvent) weight ratio ranges from 0.05 to 0.5 and the (polyphenol)/(alkoxylating agent) weight ratio ranges from 0.15 to 0.7;
- and
- (b) removing residual alkoxylating agent.
