摘要：
Experimental miscibility studies were performed on different compositions of i’PP/sPP blends, where sPP has a low syndiotacticity ([rrrr] = 81%). Combining optical microscopy, rheology, and solid state NMR spectroscopy, the miscibility of the blends was investigated at different scales in the traditionally thought to be "immiscible" iPP/sPP blends. For the composition of iPP/sPP (90/10) blend, it shows to be miscible in the melt, and furthermore, the existence of intermolecular chain interactions between sPP and ;’PP components was detected in the solid state.
