They showed that the rheological properties of phenolic polymers dissolved in chloroform (DGEBA/chloroform), (DGEDDS/chloroform) and (DGEDDP/chloroform) all exhibit the same rheological properties regardless of the temperature of (polymer/solvent) system. Rheological properties are typically applied to Non-Newtonian fluids but can also be applied to soft solids such as thermoplastics at elevated temperatures experienced during the welding process. The material properties associated with the rheological behavior include viscosity, elasticity, plasticity, viscoelasticity, and the materials activation energy as a function of temperature.

Rheological properties of polymers

The mass ratio of sodium alginate to gelatin plays a decisive role in the sol-gel transition and rheological behavior of the complexes. Differences in the sol-gel transition temperature were observed upon heating and The correlation between polymer properties (molecular weight, tacticity, side groups), on the one hand, and the resulting thermo-rheological properties of PMB, on the other hand, are investigated.

31 and yield stress) were measured and/or calculated. They found that the rheological behaviour of vaginal gels strongly depended on the type of gelling agent used; which potentially influences their spreading and retention Polymers show complex rheological behavior which needs to be considered when using or producing these kinds of materials, like the viscosity of the melt, flow behavior, viscoelastic properties, temperature-dependent behavior, glass transition temperature, aging behavior, etc. Various tests and analysis methods are employed to optimize the polymer properties until they meet all requirements. Rheology of Polymers. Rheology laboratory testing of polymers to determine the rheological (flow) properties of materials, gels and pastes, to optimise processing and properties .
