Analysis of flow instable phenomenon of polymer melts using gel permiation chromatography and multi-angle light scattering equipping with continuous viscometry (GPC-MALS)

摘要

We studied the relation between flow instable phenomenon and molecular structure of polymer chain with some commercial HDPE (High Density Polyethylene) melts. In this study we analyzed molecular structure through using gel permeation chromatography and multi-angle light scattering equipping with continuous viscometry (GPC-MALS-[η]).^sWe showed that one of the origins of the flow instable phenomenon could be ploymer chains' structure.
