Investigation of low-temperature radiation living radical polymerization of vinyl monomers with fullerene C60 by optical spectroscopy

Abstract

Water-soluble polymers of acrylamide and acrylic acid with high extent (∼90%) of C60 consumption are obtained by technique of low-temperature radiation living radical polymerization. In absorption spectra of these copolymers one can see gradually descended unstructured absorption in the range 240-700 nm, characteristic for fullerene covalent-bound or its klasters. The way of radiation initiation is used to obtain the products of high purity, because it is not necessary to embed into the system any initiators or catalyst. Latter is very important in the case of synthesis of polymers for medical purposes. Also at radiation initiation a rate of initiation reaction does not depend on the temperature and the sterilization of products takes place simultaneously. © 2007 Springer.
