본 발명은 적어도 하나의 올레핀을, (i) 적어도 두 개의 시클로펜타디에닐 유형 리간드를 포함하는 메탈로센 복합체; (ii) 붕소계 공촉매; 및 (iii) 알루민옥산 공촉매;를 포함하는 촉매와 반응시키는 단계를 포함하는 적어도 하나의 올레핀의 중합 방법에 관한 것이며, 상기 촉매는 고체 형태, 바람직하게는 고체 미립자 형태이고, 외부 담체가 없다. A process for the polymerisation of at least one olefin comprising reacting said at least one olefin with a catalyst comprising: (i) a metallocene complex said metallocene comprising at least two cyclopentadienyl type ligands; (ii) a boron cocatalyst; and (iii) an aluminoxane cocatalyst; said catalyst being in solid form, preferably in solid particulate form, and being free from an external carrier.
