Nonwoven materials obtained by electrospinning on the basis of epoxydated derivatives syndiotactic 1,2-PB

The production of chemical fibers is an urgent task. Non-woven ultra-thin materials based on thermoplastic elastomers have high physicomechanical and filtering properties. Of particular interest is the production of non-woven materials based on epoxidized derivatives of syndiotactic 1.2-polybutadiene. In this connection, the possibilities of obtaining nonwoven materials based on epoxy derivatives of syndiotactic 1.2-polybutadiene by the method of electrospinning and determining the main factors influencing the formation of fibers and the degree of orientation of fibers of syndiotactic 1.2-polybutadiene in non-woven materials were studied. Epoxidation of syndiotactic 1.2-PB was carried out by the action of tungsten oxo-peroxo complexes. The electro spinning method was used to orient oriented nonwoven materials based on syndiotactic 1.2-polybutadiene. Optimization of the process for obtaining fibers of syndiotactic 1.2-polybutadiene was carried out using the mathematical method of planning the Plaquette-Burman experiment. Investigation of the structure of nonwoven fibrous materials was carried out on a scanning electron microscope. The degree of orientation of the fibers of syndiotactic 1.2-polybutadiene was determined using the MBF program. With the use of the method of electrospinning, nonwoven materials with different degrees and variants of fiber orientation in the composition of nonwovens can be produced. The use of epoxidized derivatives of syndiotactic-1.2- polybutadiene with different content of oxirane groups allows to regulate the diameter of fibers in non-woven materials
