Abstract: 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.

Abstract: The invention relates to a cross-linking monomer with at least one sulfur atom, representable by a structure of formula (I) wherein the symbols have the following meaning: L1 is a linear, branched or cyclic, saturated or unsaturated, aliphatic or heteroaliphatic group with 2 to 10 carbon atoms; an aromatic or heteroaromatic group with 4 to 12 carbon atoms or a group with 6 to 14 carbon atoms, which comprises at least one saturated or unsaturated, aliphatic and/or heteroaliphatic residue and at least one aromatic and/or heteroaromatic residue, wherein the phosphorus atom is directly bonded with a carbon atom; V1 is a saturated or unsaturated, aliphatic or heteroaliphatic group with 2 to 50 carbon atoms; an aromatic or heteroaromatic group with 5 to 50 carbon atoms or a group with 6 to 50 carbon atoms, which comprises at least one saturated or unsaturated, aliphatic and/or heteroaliphatic residue and at least one aromatic and/or heteroaromatic residue; X1 is the same or different, O or NR3, each time it o
