Homo- and copolymers of monomers obtained by acylation of 2-[4-hydroxy(or amino)phenyl]-2-[5-(8-hydroxyquinolyl)]-propane with alpha , beta -monoolefinically unsaturated carboxylic acid halides or - anhydrides. As comonomers can be employed compounds containing one or more alpha , beta -olefinically unsaturated groups such as olefines, diolefines, acrylic acid derivatives, vinyl monomers. The polymers having molecular weights between 5000 - 500,000 can be prepared by radical or ionic chain mechanisms, in continuous or discontinuous processes. They may be used for removing metal ions from their solution, for complexing of interfering metallic impurities in thermoplastic or thermosetting resins or in form of their metal complexes as stabilizers for plastics. |
