Kuvayeva Y. Developing of the production of new thinfibrous materials based on compatibilized polymer mixtures

In the dissertation the first time it has been shown possibility to realize the specific fiber-formation in polyoxymethylene / copolyamide and polyoxymethylene / ethylene and vinyl acetate copolymer mixtures under processing by industrial extrusion equipment. The first time it has been shown that introducing of polyethylene glycol and its binary mixtures with ethylene and vinyl acetate copolymer has permitted to realize the specific fiber-formation for polypropylene / copo- lyamide mixtures with ratios corresponding to the phase inversion region. Moreover the addition of polyethylene glycol improved the moisture-absorption of polypropylene microfibers. For the first time it has been investigated properties of polypropylene / copolyamide mixture melts filled by the nanoparticles of aerosils. The results of this dissertation work give the possibility to develop the production of new nanofilled materials and materials on the basis of ultrathin polyoxymethylene fibers with high productivity when purifyingdegree is less 0,3?m.
