英文摘要 | Based on propylene heterogeneous copolymerization with the aid of RGT-aligned Ziegler-Natta catalyst, a novel in-reactor PP alloy with cross-linking EPR has been prepared through alpha, omega-diene such as 1, 9-decadiene (DD) addition. The polymerization results show that DD monomer has a good reactivity with ethylene and propylene monomers and a minor effect on the composition of copolymers. DD monomer has been successfully bonded into the backbones of ethylene-propylene random copolymer, resulting in branching and cross-linking of the EPR. The melt flow rate (MFR) of the new hiPP shows an obvious drop after the introduction of DD monomer; while the gel content increases with the increasing of DD monomer. Morphology study by SEM reveals that cross-linking EPR greatly promotes the dispersivity of rubber phase in PP matrix. The size of rubber particles reduces with the branching and cross-linking density. The results of mechanical properties tests indicate that cross-linking EPR can potentially enhance the toughness of hiPP without or with little compromise of the rigidity and processibility, which is very meaningful to achieve the rigidity-toughness balance of PP resins. |
