On of them was prepared from carboxymethyl starch CMS (degree of substitution (DS) is 1) and 2-hydroxypropyl-3-trimethylamine starch (DS = 0,8), another PEC was formed from CMS and polyethyleneimine (PEI). It is shown that the structure of PEC obtained from starch derivatives containing carboxy and tertiary amino groups is amorphous-crystalline, whereas the structure of PEC obtained from CMS and PEI is amorphous. In order to obtain metal-containing nanocomposites the chemical (NaBH<\/em><em>4<\/em><em>) and thermochemical reduction (150 \u00b0<\/em><em>\u0421<\/em><em>) of appropriate tetriary silver and copper complexes with PEC are used.
