Summary: The phase behavior of poly(ethylene‐ co ‐styrene) (PES) and poly(ethylene‐ co ‐butene) (PEB) blends has been studied. A closed‐loop phase diagram was clearly observed in this weakly interacting system as the styrene content in the PES decreased to about 1 mol‐%. At higher styrene contents, the phase loop starts to interplay with the crystallization transformation at lower temperatures.Phase diagram of PEB/PES blends. Phase boundary line is only for easy demonstration.
