ResumoBlends of linear polyethylene with two ethylene—octene copolymers of 2 and 8 mol% octene content have been prepared and their melt-phase behaviour determined by examination of quenched samples by differential scanning calorimetry and transmission electron microscopy using surface replicas. The ternary phase diagram for the system has been determined. It shows three distinct regions of liquid—liquid phase separation, all at high branch content.
