Patent ID: 10982071

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: wherein  A in each case independently is selected from H, CN, linear, branched or cyclic aliphatic or aromatic C1-C30 hydrocarbon residues;  X in each case independently is —COO— or —CON(R1)—, 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 C1-C30 hydrocarbon residues;  R1 in each case independently is selected from hydrogen and linear, branched or cyclic aliphatic or aromatic C1-C10 hydrocarbon 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; and  n in each case independently is an integer from 1 to 6.
