| Abstract: | Commercial impact copolymer polypropylene (ICP) blended with HOPE was studied to simulate those products made in polymerization process with three sequential reactors. The morphology, rheological behavior and mechanical properties of such blends were examined. Result shows that the blended HDPE could enter into the rubber phase of ICP and formed the core- shell composite particles,which made the ICP's impact strength improved considerably without a great loss of rigidity. Rheological study indicated that these blends were negative deviation blends (NDB) not in compliance with the logarithm additivity rule. DSC and DMA experiments proved an interaction between HDPE and ICP. |
