Description of the flow induced coalescence in immiscible polymer blends - advances and persisting problems
Original language description
The contribution discusses present state of art of modeling of the flow induced coalescence with respect to applicability of its results to the control of the phase structure evolution in flowing polymer blends. It is shown that the theory based on the switch between equations for matrix drainage between spherical or highly flattened droplets provides for probability, Pc, that the collision of droplets will be followed by their fusion, similar dependences on system parameters as more complicated modeling. This theory facilitates to consider the effect of the matrix elasticity on coalescence. Pc decreases with the matrix relaxation time. This decrease is small for short relaxation times but pronounced for long relaxation times. A new equation for description of the matrix drainage between flattened droplets is proposed, which is applicable for the whole range of viscosity ratios of the droplets and matrixes. Comparison of the assumptions of available theories of coalescence with charact
