FILM MATERIALS WITH TIAMULIN FUMARATE ON THE BASIS OF POLYURETHANEUREAS, WHICH CONTAINING IN THE STRUCTURE FRAGMENTS OF A COPOLYMER OF N-VINYLPYRROLIDONE WITH VINYL ALCOHOL
Аннотация:A series of hydrophilic film materials with tiamulin fumarate based on polyurethaneureas (PUU) which contain in its structure fragments of the copolymer N-vinylpyrrolidone and vinyl alcohol at various ratios of components. The structure of the obtained polymer materials was investigated by the method of IR-spectroscopy. It was established that immobilization of tiamulin fumarate occurs due to physical bonds. The introduction of the tiamulin fumarate in to PUU leads to increased physical and mechanical properties which are within the 3,0-7,3 MPa. Polymeric materials with tiamulin fumarate synthesized at ratio GMDA to VP-VA as 70 to 30 characterized by most high values of strength (7.3 MPa) and the relative elongation at break (100%) and can be offered for medical and biological tests.
