PREPARATION AND REACTIVITY OF METAL-CONTAINING MONOMERS .42. COPOLYMERIZATION OF METAL-CONTAINING MONOMERS AS A ROUTE FOR THE SYNTHESIS OF THE PRECURSORS OF HIGH-TEMPERATURE SUPERCONDUCTING CERAMICS

The preparation of HTSC ceramics based on Y-III and Bi-III was studied. The polymers were obtained by two methods: by the reaction of preliminarily synthesized polyacrylic acid (PAA) or polyacrylamide (PAAm) with Y-III, Ba-II, and Cu-II nitrates or by copolymerization of metal containing monomers (metal (Y-II, Ba-II, and Cu-II) acrylates or acrylamide complexes of metal (Bi-III, Ca-II, Sr-II, Pb-II, and Cu-II) nitrates). The copolymerization was carried out in solution, in the solid phase, or using spontaneous polymerization, which has been previously discovered by the authors. The properties of the HTSC ceramics obtained are improved when the products of copolymerization of metal containing monomers are used.
