| 摘要 |
The invention relates to a method for producing a polymer mixture. Said method comprises a first polymerization step in which monomer M is reacted by radical atom transfer polymerization in a mixture which contains a transition metal salt, an at least bidentate ligand, an atom transfer polymerization inhibitor, a reducing agent and monomer M and a second polymerization step, in which silyl group-substituted monomer S from the mixture obtained by the first polymerization step is added so that silyl group-substituted monomer S is reacted in the mixture obtained by the first polymerization step, by radical atom transfer polymerization. The polymer mixture so obtained is used as a binder additive for sealing materials.
