Mapping and control of the high-impact polypropylene morphology
Original language description
As a member of the group of heterophase polymers, the high-impact polypropylene (hiPP) consists of two immiscible phases - of porous crystalline matrix (made from isotactic polypropylene = iPP) and of soft rubbery domains (made from ethylene-propylene random copolymer = EPR) built in the pores of the iPP matrix. In such material the hardness of crystalline iPP is supplemented with the impact toughness due to a good dispersion of EPR domains with suitable sizes. The mapping of the hiPP morphology and itsevolution during the polymerization process is crucial for understanding how various manufacturing factors influence the hiPP morphology. The distribution and sizes of pores within the iPP particles (and subsequent EPR distribution within hiPP particles) are determined by type of Ziegler-Natta (Z N) catalyst and by reaction conditions. In this contribution we discuss the differences between iPP and hiPP samples grown on different Z N catalysts. Also EPR content and EPR composition are p
