Application of theory to extrusion of polyethylene [PDF]
, 1955 This thesis reviews the theory of isothermal melt extrusion beginning with the writings of early researchers up to its present state. The isothermal extrusion of a near-Newtonian liquid is compared to polyethylene, using five different extrusion screws ...

Interfacial silica nanoparticles stabilize cocontinuous polymer blends [PDF]
arXiv, 2015 We investigated the formation of cocontinuous structures in polymer blends. These polymeric bijels (bicontinuous interfacially jammed emulsion gels) were composed of polystyrene oligomer, polybutene and fluorescent hydrophobic silica nanoparticles.
