| description | The present invention provides a supported hybrid catalyst, and a method for preparing a polyolefin by using same, the supported hybrid catalyst comprising two or more types of transition metal compounds having a specific chemical structure, and thus a polyolefin, particularly, a high-density polyethylene, having a molecular structure optimized to improve the tensile strength of a chlorinated polyolefin compound can be prepared.
La présente invention concerne un catalyseur hybride supporté et un procédé de préparation d'une polyoléfine faisant appel à celui-ci, ledit catalyseur hybride supporté comprenant au moins deux types de composés de métaux de transition ayant une structure chimique spécifique. Ainsi, une polyoléfine, en particulier un polyéthylène haute densité, ayant une structure moléculaire optimisée pour améliorer la résistance à la traction d'un composé de polyoléfine chlorée, peut être préparé(e).
