FIELD: biologically active polymer materials.
SUBSTANCE: invention relates to polypropylene compositions showing bactericidal activities and intended for manufacture of any products through molding and extrusion while being suitable for fabrication of polypropylene fibers for water and air filters used in various industry fields and in medicine. Bactericidal polymer composition of invention is composed of polymer and bactericidal additive, said polymer being. in particular, polypropylene in amount 97.00 to 99.92% and said additive (0.03-1.00%) being silver phosphate, silver thiosulfate, or silver stearate. Composition further contains 0.05 to 2.00% of oleic acid amide (Finawax O).
EFFECT: imparted high bactericidal activity extending functional qualities of composition allowing use thereof in various industry fields.
