| 英文摘要 | activated by [ph3c][b(c6f5)(4)], dimethylpyridylamidohafnium complex exhibited high performance in the copolymerization of propylene with 3,3-dimethyl-3-sila-1,5-hexadiene (dmshd), producing high molecular weight random copolymers without pendent vinyl groups and cross-linking. the effects of the comonomer incorporation on chain microstructure, crystallinity, thermal properties and final mechanical properties were thoroughly explored by c-13 nmr, wide-angle x-ray scattering, dsc and tensile tests, respectively. the comparison of microstructure and mechanical properties between poly(propylene-co-dmshd) and poly(propylene-co-hd) clearly indicates that the structures of the comonomers have significant effects on the chain microstructure, crystal structure and the final properties of the copolymers. all copolymer samples showed great enhancement of ductility and flexibility. it was noteworthy that the poorly crystalline copolymers containing small amount of crystalline in the amorphous matrix exhibit a typical thermoplastic behavior. thus, a series of pp materials with different physical properties ranging from stiff plastics to semicrystalline flexible plastics to thermoplastic elastomers could be obtained by simply changing the monomer incorporation.
