Summary Blends of polyethylene (PE) with very low TLCP concentrations have viscosity ratios of 10(-6) to 10(-4), and viscosity reductions > 90% are observed. This viscosity reduction is generated by a number of mechanisms in sequence; wall slip being only one. The others are droplet coalescence, deformation and fibril formation, plus effects associated with the TLCP's ability to self-order and align when under shear, leading-to a phase transition in the nematic-isotropic biphase. Intercomponent adhesion and interfacial tension also influence the droplet dynamics.
