Conduction carriers and localized spin centres in carbon black doped polyester resin

Abstract

The temperature dependences of ESR spectra of a polyester resin doped with various amounts of acetylene carbon black are investigated. The existence of two types of paramagnetic centres is ascertained i.e. localized paramagnetic centres and paramagnetic conduction carriers. Contributions of both types of paramagnetic centres in polymer-carbon black mixtures to the ESR spectrum are determined in relation to the carbon black content. The nature of radical type interactions of polymer macromolecules with various admixtures of acetylene carbon black is discussed. [Russian text ignored].
