The aim of this contribution is to compare the nanofibrous webs in dependence on the preparation of polymer solution from which are created. The solutions formed by polyvinylbutyral (PVB) solved in methanol at different concentrations were prepared in two ways - either using a vibrating shaker or a magnetic stirrer. The principal difference consists in invasive and non-invasive effect of the individual approaches and the consecutive mild changes in the molecular architecture. The rheological characterization of both types of PVB solutions was carried out an electrocell housed in the rotational rheometer. The nanofibrous webs obtained by an electrospinning process were analyzed by means of scanning electron microscopy. There was found a correspondence between the differences in quality of the nanofibrous webs and the rheological characteristics of either solutions.
