Investigation of the morphology of polymer mixtures depending on flow conditions of melts

Investigation o f the Morphology of Polymer Mixtures Depending on Flow Conditions of MeltsRecently, attention has been increasingly concentrated on the problem of formation of fibrillar structures in the flow of polymer melts.'-9In this connection, it is important to define the tendency to form fibrillar and stratified structures depending on the basic parameters which determine the conditions of flow of melts of mixtures in ducts.The conditions of freezing or relaxation of the forming structures in the outflow of two-phase polymer mixtures from the ducts are the most important factors here.
