A process for the preparation of a reaction product (A) comprises the following stage (i): (i) Reaction, under free radical conditions, of a reaction mixture comprising at least one monomer (a), capable of free radical reaction, in the presence of at least one compound of the formula (I) where R1 to R4, independently of one another, are each hydrogen, methyl or a group which stabilizes radicals and/or is bulky and which is selected from an unsubstituted or substituted, linear or branched alkyl of two or more carbon atoms, a cycloalkyl, alcohol, ether, polyether, amine or aralkyl radical, a substituted or unsubstituted aromatic, heterocyclic or olefinic hydrocarbon, a halogen atom, a substituted or unsubstituted, linear or branched alkenyl or alkynyl group, -C(O)R5, -C(O)OR5, -CR5R6-O-R7, -O-C(O)R5, -CN, -O-CN, -S-CN, -O-C=NR5, -S-C=NR5, -O-CR5R6-CR7R8NR9R10, -N=C=O, -C=NR5, -CR5R6-Hal, -C(S)R5, -CR5R6-P(O)R7R8, -CR5R6-PR7R8, -CR5R6-NR7R8, -CR5R6(OR7)(OR8), -CR5R6(OR7)(NR8), -CR5R6(NR7)(NR8), an anhydride, acetal or ketal group, -SO2R5, an amidine group, -NR5C(S)NR6, -NR5C(S)-OR6, -N=C=S, -NO2, -C=N-OH, -N(R5)=NR6, -PR5R6R7, -OSiR5R<highlight |
