Metal-polymer composites (MPC) based on copolymers of polypropylene glycol maleate phthalate with acrylic acid and metallic gold and silver were synthesized for the first time. The structure of nanocomposites is characterized with the help of microscopy and spectroscopy. Antimicrobial activity of novel metalpolymeric complexes based on silver and gold was studied. Metal-polymeric complexes were stabilized for the first time with polymeric matrix based on the copolymers of polypropyleneglycolmaleatephthalate with acrylic acid (p-PGMPh/AA:Ag, p-PGMPh/AA:Au). Obtained nanocomposites contain the nanoparticles of silver and gold of rhomboidal and cylindrical shapes with the sizes of 40-50 and 35-50 nm correspondingly. The size of more than 80 % of the nanoparticles are from 20 to 50 nm and has a spherical and rhombic shape. For determination of antimicrobial activity of the MPC the reference test-microorganisms such as facultativeanaerobe gram-positive Staphylococcus aureus, aerobic gram-positive spore-forming Bacillus subtilis, gramnegative facultative anaerobe of Escheri.hia coli, aerobic Pseudomonas aeruginosa and yeast fungi.andida albicans have been used. The resulting nanocomposites are stable and promising for the creation of new photochromic and nonlinear optical materials, as well as for using in medicine in the development of antiseptic and antimicrobial materials that are needed during a pandemic.
