Description

ABSTRACT:
The invention concerns new organo-boron compounds with strong aerobic initiator action to start polymerizations but with improved stability when in contact with atmospheric oxygen. The boron is connected to the molecule predominantly by boron to carbon and optionally boron to hydrogen bonds. The organo-boron compounds are characterized by the fact that the boron containing radicals are connected to an organic polymer matrix that is at least largely nonreactive when exposed to atmospheric oxygen. The boron containing radicals are preferably directly connected to a carbon atom of the polymer matrix by at least one valence of the respective boron atom. The advantageously viscous-fluid to solid masses that are preferably largely free of solvents contain especially hydro-boron radicals and/or organic boron radicals that can have alkyl, cycloalkyl and/or aryl radicals as substituents.
