A polymerisation catalyst comprising (1) a transition metal compound of Formula (A), and optionally (2) an activator, wherein Z is 5-membered heterocyclic containing carbon, nitrogen and at least one other selected from nitrogen, sulphur and oxygen, the remaining atoms in the ring being nitrogen and carbon; M is a metal from Group 3 to 11 or a lanthanide metal; E
1
and E
2
are divalent hydrocarbon, heterocyclic or heterosubstituted derivatives of these; D
1
and D
2
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 zero or integers so that X and L satisfy the valency/oxidation state of M, characterized in that the complex contains at least one polymerisable olefinic double bond which is present in, or substituent to, at least one of the atoms, groups or ligands represented by Z, E, D and L. The catalyst binds to the forming polymer providing product with good particle morphology.
一种聚合催化剂,包括(1)式(A)的过渡金属化合物,以及可选的(2)活化剂,其中Z是含有碳、氮和至少一种从氮、硫和氧中选择的其他元素的5元杂环,环中其余原子为氮和碳;M是3到11组或镧系金属中的金属;E1和E2是二价的碳氢化合物、杂环或这些的杂基衍生物;D1和D2是给体原子或基团;X是负离子基团,L是中性给体基团;n=m=0或1;y和z为零或整数,以使X和L满足M的化合价/氧化态,其特征在于该配合物至少含有一个聚合性烯烃双键,该双键存在于Z、E、D和L所代表的原子、基团或配体中的至少一个中或代替其中之一。催化剂与形成的聚合物结合,提供具有良好颗粒形态的产品。
