Aromatic polyether-polyamine polymer, process for the preparation of this polyamine and its use in the preparation of polyurethanes

摘要

The invention relates to polymer-containing polyether polyamines with terminal, aromatically bound amino groups and a process for the preparation of polyether polyamines with aromatic amino groups by radical in-situ polymerization or graft polymerization with one or more ethylenically unsaturated monomers, preferably with acrylonitrile / styrene -Mixing. According to this procedure, polymeric (1-60% by weight polymer), aromatic polyether polyamines with a low viscosity and easy processability are obtained. Furthermore, the use of polyether-polyamines prepared in this way and having a relatively low viscosity and containing polymers containing aromatic amino groups is claimed as a structural component in polyurethane syntheses.
