| 简介 |
The present invention provides : a method for manufacturing a catalyst, useful in manufacturing a conjugated diene-based polymer, in which the catalyst is manufactured by preliminarily polymerizing a rare-earth metal compound, an alkylating agent, a halogen compound, and a conjugated diene-based monomer, and then aging the same at a specific temperature for a specific time, thereby exhibiting excellent catalytic activity and polymerization reactivity, having an excellent modification rate, and having improved mixing properties; a catalyst; and a method for manufacturing the conjugated diene-based polymer by using the same.COPYRIGHT KIPO 2019 |
