Description
Summary:Reverse gas chromatography and mechanical dynamic spectroscopy have been used to study the effect of fillers of varied nature on the thermodynamics of the interactions and visco-elastic properties of binary PE-POM and PS-PBMA blends over a wide concentration region of the blends and contents of fillers in the regions of extremal changes in properties. The introduction of a filler into the system leads in a certain region of compositions to rise in the thermodynamic stability of the blend. In this region of compositions and contents of fillers smoothing or disappearance of the maxima are observed in the concentration dependence of the real part of the complex shear modulus. A clear relationship has been established between the thermodynamic state of the filled blends of polymers in the melt and their physicomechanical characteristics in the solid state.
