Abstract (en)
[origin: WO2021156033A1] The invention relates to a process for the radical polymerization for preparing a copolymer, using specific monomers A, which have a glass transition temperature Tg of at least 0° and specific monomers B, which contain an aromatic heterocyclic group that contain at least one nitrogen atom in the ring. The invention also relates to copolymers that are obtained by the radical polymerization, to the use of same as accelerators in a curing reagent for adhesive compounds, and to adhesive strips containing same.
