Modeling The Rheological Behaviour Of The Low Density Polyethylene/ Thermoplastic Starch Blend

The rheological behavior of TPS and its blend with other synthetic polymer is very complex, because its gel like behavior and its high elasticity. This complexity is moreapparent when compatibilizer is added to the blend. The most common model which is used for modeling the elasticproperties of the blends is Palierne1,2 which is not appropriatefor modeling the compatibilized blends3. In this study the Fractional Zener model (FZM) was used to investigate thestructure of LDPE/TPS blend with and without the compatibilizer.
