There were rules of structure forming in the blend melts of polypropylene/poly(vinyl alcohol)/glycerol (PP/PVA/(Glyc) with PP/PVA ratio of 30/70 % mass., and glycerol content of 7,0 – 15,0 % mass established. It is shown, that glycerol concentration increase is not changing off the PP structure forming type in the PVA matrix. When at processing and at increase of plasticizer concentration, the average diameter of microfibers (MFs) and part of  films in the extrudate are increasing simultaneously also.  There were no Glyc influence on crystallization process in melt founded in: the crystallization temperature (ТCr) at Glyc content of 7.0 % mass. are decreasing on, and, there are no PP crystallization peak through one’s amorphization. There are the crystallization degree of PP observed as decreasing one, through its highly-dispersed state as thin MFs. When despite to fact, then  some decrease of spinning ability because of shear viscosity have place through, and, then, those can be processing on usual equipment.
