i) Hf 및 Zr로부터 선택되는 금속 원자; ii) 포스핀이민 리간드; iii) 아미도-에테르 리간드 및 적어도 하나의 다른 보조(ancillary) 리간드를 함유하는 유기금속 착물의 신규한 군. 올레핀 중합 촉매로서, 활성화제와 조합된, 이러한 착물의 용도가 기재된다. 상기 촉매는 에틸렌과 알파 올레핀(예컨대, 1-부텐; 1-헥센 또는 1-옥텐)의 공중합에 특히 효과적이며, 높은 생산성에서 양호한 공단량체 혼입(incorporation)으로 고분자량 공중합체(Mw가 25,000 초과)의 생산을 가능하게 한다. Provided in this disclosure are organometallic complexes that contain i) a metal atom selected from Hf and Zr; 2) a phosphinimine ligand; 3) an amido-ether ligand and at least one other ancillary ligand. The use of such a complex, in combination with an activator, as an olefin polymerization catalyst is demonstrated. The catalysts are effective for the copolymerization of ethylene with an alpha olefin (such as 1-butene, 1-hexene, or 1-octene) and enable the production of high molecular weight copolymers (Mw greater than 25,000) with good comonomer incorporation at high productivity.
