Abstract
Theoretical model representing rheological properties of multicomponent blends as functions of their composition and properties of individual components was proposed. Applicability of this model was experimentally verified for two binary blends. In both cases a good agreement of theoretical predictions with experimental data was stated.

Melt-miscible polymer blends of poly(ethylene oxide)/atactic poly(methyl methacrylate (PEO/ a-PMMA) were prepared by melt-mixing and characterized by pressure-volume-temperature (PVT) dilatometry in the pressure and temperature range of 0 to 200 MPa and 20 to 200ЊC, respectively. The PVT data were a
## Abstract A family of conformational rheological models for multi‐component miscible polymer blends is developed using a modified form of the Poisson bracket formulation. Two conformation tensors called **c**~1~ and **c**~2~ are introduced to show the orientation of the first and the second compo
