Ethyl.ne-propyl.ne bl.ck copol.mer(EbP) is a vital.component in impact pol.propyl.ne copol.mer(iPC), yet its distribution in the mul.iphase composite material.and how it infl.ences the phase structure and the mechanical.properties are not wel. understood. in this work,four iPCs were investigated by atomic force microscopy-infrared(AFM-iR) to assess the phase compositions in situ, based on which in conjunction with the chain microstructure information obtained ex situ the distributions of the copol.mer components were derived for each al.oy. For the iPCs whose EbP comprises l.ng P and l.ng E segments, the EbP fraction was found to phase separate from the rubber and the PP matrix to form the cores of the disperse particl.s with the E-P segmented copol.mer(EsP). in contrast, in the iPC with EbP composed of l.ng P and short E segments, the EbP fraction formed an outer shel. for the rubber particl.s with the cores comprising the EsP al.ne, and this iPC, containing a l.wer E comonomer content than its counterpart, exhibited both better impact resistance and higher fl.xural.modul.s. These resul.s cl.rify how the chain structure of EbP governs the phase morphol.gy in iPC, which in turn impacts the properties of the composite material.
