| 英文摘要 | Morphological features of isotactic polypropylene (iPP) and high impact polypropylene (hiPP) particles produced in a multistage polymerization process were investigated by field-emission electron microscopy (FESEM) and transmission electron microscopy (TEM) techniques. Study was mainly focused on architecture of iPP particle and distribution of elastomer phase (EPR) within the preformed iPP matrix. The iPP particle is an agglomerate of many subglobules (ca. several to hundred microns in diameter), while the subglobule in turn is formed by a great deal of primary globules (ca. 100 nm in diameter). Large macropores between the subglobules and finely distributed micropores within the subglobule constitute a network of pore inside the iPP particle. Ethylene/propylene comonomers can diffuse into the macro- and micropores and copolymerize on catalyst active sites located on periphery of the pores, forming elastomer phase inside.
