Abstract (en)
[origin: WO2013030261A1] Method for producing polymers by means of controlled radical polymerisation, wherein the polymerisation of one or several radically polymerisable monomers of general formula (I), where R1, R2, R3 are H, C1-C4 alkyl, R4 is C(=O)OR5, C(=O)NHR15, C(=O)NR5R6, OC(=O)CH3, C(=O)OH, CN, aryl, hetaryl, C(=O)OR5OH, C(=O)OR5Si(OR5)3, halogen, NHC(O)H, P(=O)(OR7)2, R5 is C1-C20 alkyl, R15 is C1-C20-alkyl, R6 is C1-C20 alkyl, and R7 is H, C1-C20 alkyl, occurs in the presence of a. one or several catalysts containing Cu in the form of Cu(0), Cu(l), Cu (II) or mixtures thereof, b. one or several initiators selected from the group of organic halogenides or pseudohalogenides, c. one or several ligands, d. optionally one or several solvents, and e. optionally one or several inorganic halogenide salts, said method consisting of the following steps i) addition of the catalyst a., ii) optional addition of monomers of general formula (I), iii) optional addition of solvent d., iv) addition of ligand c., v) addition of initiator b., vi) addition of monomers of general formula (I), and vii) optional addition of inorganic halogenide salts e., on the proviso that the addition of at least some of the monomers of general formula (I) occurs immediately before or shortly after the last of the steps i), iv) and v).
