Nucleation and entanglement of cyclic polyethylene

Research output: Contribution to conferencePaperpeer-review


Previously, we have shown the hierarchised model of entanglements of polymer chains based on melt annealing time Δt dependence of nucleation rate I of "nascent" linear polyethylene (nascent L-PE). This work showed the validity of above model and role of "knot" entanglement in the nucleation of polymers using cyclic polyethylene (C-PE) which can not form the knot entanglement. We found that I of C-PE was remarkably larger than that of L-PE. Moreover, we found that I of C-PE monotonically decreased with increasing Δt. These imply that the knot entanglement plays an important role in the nucleation.
