| Research Abstract |
We found that the formation of shish-kebab structure of cyclic polyethylene is more difficult than that of liner polyethylene (L-PE). This indicates that most entanglement species of C-PE are simpler than that of L-PE. In this work, for C-PE, we attempted to introduce more complicated entanglements by blending of C-PE matrix and small amount of L-PE. We clarified that knot entanglements play an important role in the formation of shish-kebab structure of C-PE.
