Twisted polymers: Structural reorganization in macromolecular network through metal ion coordination

Authors


Abstract

The alkylation of flexible styrene–divinylbenzene copolymer, with 5-chloromethyl-8-hydroxyquinoline in the “impregnated” dry state in the presence of aluminum chloride in nitrobenzene, is accompanied by structural reorganization. The polymer external shape is twisted and the internal structure constringes or expands, according to the impregnation method. The process of the “twist” polymer formation can be explained by the coordination of aluminum ions by the oxine ligand concurrently with the alkylation.
