| 中文摘要 | ethylene-propylene copolymerization, using [(ph)nc(r-2)chc(r-1)o](2)ticl2 (r-1 = cf3, ph, or t-bu; r-2 = ch3 or cf3) titanium complexes activated with modified methylaluminoxane as a cocatalyst, was investigated. high-molecular-weight ethylene-propylene copolymers with relatively narrow molecular weight distributions and a broad range of chemical compositions were obtained. substituents r-1 and r-2 influenced the copolymerization behavior, including the copolymerization activity, methylene sequence distribution, molecular weight, and polydispersity. with small steric hindrance at r-1 and r-2, one complex (r-1 = cf3; r-2 = ch3) displayed high catalytic activity and produced copolymers with high propylene incorporation but low molecular weight. the microstructures of the copolymers were analyzed with c-13 nmr to determine the methylene sequence distribution and number-average sequence lengths of uninterrupted methylene carbons. |
