Tensile moduli of co-continuous polymer blends

Co-continuous blends of polyethylene with polypropylene or polystyrene are shown to exhibit high tensile moduli. The experimental results exceed predi ctions of the moduli using existing models for co-continuous morphologies, and approach the level of the parallel model. These high moduli are found t o be isotropic to a good degree, in contrast to fibrillar polymer blends wh ich can have such high moduli only in one direction.
