ABSTRACT OF THE DISCLOSURE Homo- and copolymers of monomers obtained by acylation of 2-[4-hydroxy(or amino)phenyl]-2-[5-(8-hydroxyquinolyl)_7-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 interferring metallic impurities in thermo-plastic or thermosetting resins or in form of their metal complexes as stabilizers for plastics. |
