Abstract: Abstract Phase selective nucleation of single chain isotactic polypropylene (iPP) into specific crystalline polymorphs is enabled by heterogeneous nucleating agents. Molecular dynamics simulations were used to investigate the ordering of isolated iPP chains over ideal… read more here.

Abstract: One of the most important nonlinear rheological phenomena in flowing polymeric materials is the stress overshoot under start-up shear at sufficiently high shear rates γ, i.e., γ > τd–1, where τd is the terminal relaxation… read more here.
