New type of metal-containing polymers— metallic clusters in polymer matrices☆

The results of study of metallopolymers of a new type are outlined-metallic clusters in PE and PTFE polymer matrices obtained on thermal degradation of the organic salts of the metals: iron, nickel and chromium or their carbonyls in the polymer melt. The NMR (continuous method) was used to study on the 1H and 19F nuclei, the mechanism of penetration of the clusters of iron, nickel and chromium metals into the polymer matrices. It is shown that the subatomic particles of the metals (clusters) reduce the mobility of the molecular chains, raising the thermal stability of the polymer compositions. The method of small angle X-ray scatter is used to determine the size distribution of the metallic clusters and the periodicity of their disposition in the matrix.
