The thermodynamic and rheological properties of polymer melt mixtures

Regardless of the phase of the mixture components (both crystalline or amorphous, or one crystalline, the other amorphous), a low thermodynamic stability of the system...

Description
Summary:Melts of polymer mixtures have been found to possess a correlation between their rheological properties and thermodynamic stability. Regardless of the phase of the mixture components (both crystalline or amorphous, or one crystalline, the other amorphous), a low thermodynamic stability of the system will mean a substantial reduction of the viscosity below that of additivity, and vice versa. An attempt is being made to explain the observed mechanism by the type of phase separation mechanism of such systems.
