Abstract
The invention relates to the use of sulfonic acid esters of the following Formula 1 and/or Formula 2, individually or as a mixture of more than one thereof, as regulators in polymerization reactions of radically polymerizable, ethylenically unsaturated monomers: whereinA in each case independently is selected from H, CN, linear, branched or cyclic aliphatic or aromatic C-Chydrocarbon residues;X in each case independently is —COO— or —CON(R)—, wherein the binding to A occurs via O or N, or is absent if A is an aromatic hydrocarbon residue or CN;B in each case independently is selected from linear, branched or cyclic aliphatic or aromatic C-Chydrocarbon residues;Rin each case independently is selected from hydrogen and linear, branched or cyclic aliphatic or aromatic C-Chydrocarbon residues, which are optionally substituted with one or more OH groups, wherein the aliphatic hydrocarbon residues are optionally interrupted by one or more oxygen atoms; andn in each case independently is an integer from 1 to 6.
