    • Process for making a copolymer by copolymerising (1) ethylene with (2) at least one comonomer selected from aliphatic C3-C20 alpha-olefins and (3) 5-ethylidene-2-norbornene, including contacting the monomer with a catalyst comprising a transition metal compound having the following Formula A, and an activating quantity of a suitable activator of the formula shown herein, wherein Z comprises a five-membered heterocyclic group, the five membered heterocyclic group containing at least one carbon atom, at least one nitrogen atom and at least one other hetero atom selected from nitrogen, sulphur and oxygen, the remaining atoms in the ring being selected from nitrogen and carbon; M is a metal from Group 3 to 11 of the Periodic Table or a lanthanide metal; E1 and E2 are divalent groups independently selected from (i) aliphatic, hydrocarbon, (ii) alicyclic hydrocarbon, (iii) aromatic hydrocarbon, (iv) alkyl substituted aromatic hydrocarbon, (v) heterocyclic groups and (vi) heterosubstituted derivatives of said groups (i) to (v); D1 and D2 are donor atoms or groups; X is an anionic group, L is a neutral donor group; n=m=zero or 1; y and z are independently zero or integers such that the number of X and L groups satisfy the valency and oxidation state of the metal M.
    • 通过使(1)乙烯与(2)至少一种选自脂族C 3 -C 20α-烯烃和(3)5-亚乙基-2-降冰片烯的共聚单体共聚制备共聚物的方法,包括使单体与包含过渡金属的催化剂接触 具有下式A的金属化合物和活化量的本文所示式的合适的活化剂,其中Z包括五元杂环基,含有至少一个碳原子的五元杂环基,至少一个氮原子和 至少一个选自氮,硫和氧的杂原子,该环中的剩余原子选自氮和碳; M是元素周期表第3至11族的金属或镧系金属; E1和E2是独立地选自(i)脂族,烃,(ii)脂环族烃,(iii)芳族烃,(iv)烷基取代的芳族烃,(v)杂环基团和(vi)所述基团的杂取代衍生物 (i)至(v); D1和D2是供体原子或基团; X是阴离子基团,L是中性给体基团; n = m =零或1; y和z独立地为零或整数,使得X和L基团的数量满足金属M的化合价和氧化态。
