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