OBTAINING ANTIBACTERIAL COMPOSITION MATERIAL BASED ON THE COPOLYMER OF SALICYLIC ACID ALLYL ETHER WITH METHYL METHACRYLATE AND ABS AND STUDYING PHYSICAL-MECHANICAL, THERMOPHYSICAL, ANTIMICROBIAL PROPERTIES

ABS (acrylonitrile-butadiene-styrene copolymer) based antibacterial composition materials (CM) were obtained and their properties were studied using the copolymer of allyl ester of salicylic acid with methyl methacrylate as an antibacterial additive. It was determined that the addition of 4, 12, 20 wt % salicylic acid allyl ester copolymer with methyl methacrylate to the composition of the ABS composite material practically does not affect its physical-mechanical properties, but the thermal resistance properties increase by increasing the amount of the additive. The antimicrobial properties of the obtained composition materials were studied. Staphylococcus aureus (S.aureus) from Gram-positive microorganisms, Ecoli from Gram-negative bacteria, blue-green pus bacillus from pigment-forming bacteria (P.aeruginoza), and C.albicans from Candida genus were taken as test cultures for their antifungal and antibacterial properties. MPA (meat-peptone agar) was used for the cultivation of bacteria and Saburo nutrient medium for the cultivation of fungi, and the experiments showed that no change occurred in any of the obtained compositions either visually or microscopically. It was determined that the obtained polymer composite materials have both bactericidal and fungicidal properties
