Abstract
  Describing the solidification process is very important in polymer processing. In polypropylene (PP), the increase of viscosity, named stiffening or hardening, is determined by a rise in crystallinity. When PP flows in a channel or is stretched on a chill roll, the stress induces an anticipated crystallization ...  Read More

Abstract
  Dimethylbenzylidene sorbitol (DMDBS) is a common nucleating/clarifier agent used in polypropylene (PP). So many researchers have looked at different aspects of incorporating this additive on crystallization behavior of PP. The current study has focused on a rather new subject and that is the role of ...  Read More

Polymer processing
Rheological, thermal and tensile properties of PE/nanoclay nanocomposites and PE/nanoclay nanocomposite cast films

Mehdi Hajiabdolrasouli; Amir Babaei

Volume 5, Issue 1 , January 2018, , Pages 47-58

https://doi.org/10.22063/poj.2017.1500

Abstract
  The effects of three different mixers, two different feeding orders and nanoclay content on the structure development and rheological properties of PE/nanoclay nanocomposite samples were investigated. Fractional Zener and Carreau–Yasuda models were applied to discuss the melt linear viscoelastic ...  Read More
