摘要

Two polyethylene/polypropylene (PE/PP) in-reactor alloy samples were synthesized by multi-stage gas-phase polymerization using a spherical Ziegler-Natta catalyst. The alloys show excellent toughness and stiffness. FTIR, ~(13)C-NMR and thermal analysis proved that the alloys are mainly composed of polyethylene, PE-block-PP copolymer and polypropylene. There are also a few percent of ethylene-propylene segmented copolymer with very low crystallinity. The block copolymer fraction accounts for more than 25 % of the alloy. The role of the block copolymer as compatibilizer between PE and PP is believed to be the key factor that results in the excellent toughness-stiffness balance of the material.
