Abstract

It has been known that Temperature Rising Elution Fractionation(TREF) is the most effective technique for investigating the microstructure of semicrystalline polymer especially polyolefins, such as PE and PP. Moreover, TREF was also applied for determining the degree of branching which affected on their mechanical properties. In the present work, the influence of medium polarity on physical properties of fractionated polymers was investigated. The commercial HDPE resins were used in this study. It was found that using mixed solvent with higher polarity can enhance the crystallization rate of polymers while the physical properties of the fractionated polymers obtained from both ones, using non-polar solvent and mixed solvent were not different significantly.
