Simulation of thermodynamic properties and molecular weight of sPPClay composites using HYSYS software

Abstract EN

The investigation of molecular weight and thermodynamic properties of polyolefin composites is needed to provide a better understanding of the macromolecular and molecular level affect on final thermal applications.

HYSYS software was used to estimate molecular weight and thermodynamic properties including: critical temperature (Tc), critical volume (Vc) and eccentricity (Ec) for sPP/clay composites, moreover, the influence of clay content on thermodynamic properties and molecular weight was investigated.

A set of sPP/clay composite samples was used with a variety of re-enforce material (Chinese clay) between 2 %.

and 10%.

It was found increased clay content led to a gradual increase in thermodynamic properties and molecular weight of samples.

This investigation validates the fact clay contents affect both the macroscopic and microscopic (mechanical and chain dynamics) properties of the polymer composites.
