| 中文摘要 | the scandium dialkyl complex lsc (ch2sime3)(2) (l = (2, 6-ipr(2)c(6)h(3))nc(me)chpph2 n-(2, 6-me2c6h3)) activated with [ph3c] [b(c6f5)(4)] could initiate ethylene and propylene copolymerization with high activity (7. 5 x 10(5)g(pe) mol(-1) h(-1) (10(5) pa)(-1)) under the conditions of room temperature (30 degrees c) and atomphere pressure (1. 0 x 10(5) pa). the influence of comonomer feed content and polymerization temperature on activity and the composition of the copolymers using lsc (ch2sime3)(2)/[ph3c][b(c6f5)(4)] catalytic system were investigated. an increase in the initial propylene feed content leads to the increase in the incorporated propylene content of the resulting copolymer. at 30 degrees c, the highest activity and incorporation of propylene were achieved. determination of the reactivity ratios shows a much high reactivity for ethylene (r(e) = 29. 75 and r(p) = 0. 015). the resultant copolymers are elastomers having random sequence distibution of the two monomeric units evidenced by c-13-nmr spectroscopy and dsc analyses. |
