Description
Summary:The influence of the molecular mass of poly-N-vinylpyrrolidone on the rheological, visco-elastic, relaxation properties of solutions and on their structure and stability of the process of obtaining fibers by electrospinning is considered. The critical values of the concentration and molecular mass of the polymer for carrying out stable electrospinning of the fiber are established, and the relationship between the molecular mass and the concentration, viscosity of the solutions, and technological parameters of the spinning process is determined.
