Software module for the prediction of a-Olefin diffusion coefficient in semi-crystalline polyolefins

Software Module for the Prediction of a-Olefin Diffusion Coefficient in Semi-Crystalline Polyolefins:

A software module was developed for the prediction of the a-olefin diffusion coefficient in semi-crystalline polyolefins. The model was built under the Studio Fortran environment and is based on free-volume concepts in which the components in the system are envisioned to migrate by jumping into free-volume holes formed by natural fluctuations.

The predictive capabilities of the free volume diffusion model were demonstrated by comparing the predictions of ethylene diffusion coefficient in PE of different crystallinities with the corresponding experimental data obtained by the Borealis BORSTAR process.
