Abstract

A process for preparing a reaction product (A), comprising the following stage (i):(i) reacting under free-radical conditions a reaction mixture comprising at least one free-radically reactable monomer (a) in the presence of at least one free-radical initiator and of a compound (I) of the formula:  in which R1 to R4 each independently of one another are hydrogen, a substituted or unsubstituted alkyl radical, cycloalkyl radical or arakyl radical, or an unsubstituted or a substituted aromatic hydrocarbon radical, with the proviso that at least two of R1 to R4 are an unsubstituted or a substituted aromatic hydrocarbon radical in aqueous phase.
