Lateral carbamate groups and activated with actinic radiation groups-containing copolymers, processes for their preparation and their use

Lateral containing primary and / or secondary carbamate groups (a12) and activated with actinic radiation groups (a31) copolymers (A), preparable by reacting I. in a first process step (A1) a monomer containing (A11) a group of the general formula I: CH in which the variable R stands for a hydrogen atom, a halogen atom, a nitrile group or an alkyl group having 1 to 10 carbon atoms, and (A12) a primary and / or secondary carbamate group, and (A2) a monomer containing (A21) a radically or ionically polymerisable, olefinically unsaturated double bond and (A22) a with the carbamate groups (a12) and do not react with the double bond (a21) non-polymerizable reactive functional group, copolymerized, whereby the copolymer (a1 / a2) results, and II. In a further method step, the copolymer (a1 / a2) with (A3) a compound containing (A31) can be activated with actinic radiation and (A32) a to the reactive functional group (a22) having complementary reactive functional group, reacting, whereby the resulting copolymer (A); Processes for their preparation and their use.
