Abstract
Official abstract text for this publication.
The present invention relates to a preparation method of olefin polymers using a catalyst composition containing a transition metal compound. In detail, the present invention provides a preparation method of olefin polymer using a catalyst composition comprising a transition metal compound, wherein the preparation method comprises introducing a scavenger to a continuous solution polymerization reactor in a specific range of amount to give the olefin polymer with good productivity.
First claim
Opening claim text (preview).
The invention claimed is: 1. A preparation method of olefin polymer from olefin monomer using a catalyst composition comprising a transition metal compound and one or more of cocatalyst compounds represented by the following Formulae 6 and 7, wherein the preparation method comprises a step of introducing a scavenger to a reactor in the amount of 0.443 to 3.103 times the total content of water, expressed as a molar ratio, and the scavenger comprises a compound represented by Formula…
