Abstract
AbstractThe method of “onium polymerization” was used for the preparation of conjugated polymers with quaternary nitrogen atoms in the main chain. The polymerization was studied for the case of 4‐chloropyridine, 4‐bromopyridine, and 4‐chloromethylpyridine. Poly‐4‐chloropyridine has increased electroconductivity and contains a considerable number of paramagnetic particles. The introduction of methylene groups between pyridinium nuclei results in the disappearance of this property. Poly‐4‐chloropyridine is soluble only in water, hydrolyzing rapidly to form pyridylpyridone and hydroxypyridine. Under the action of ammonia poly‐4‐chloromethylpyridine is transformed to the polymeric ilide.
