Abstract
The present invention relates to a method for preparing a liquid rubber, and relates to a method for preparing a liquid rubber, including performing polymerization reaction of a conjugated diene-based monomer in the presence of an organic solvent and a catalyst composition (S10), wherein the catalyst composition includes a catalyst including a compound represented by the following Formula 1, and a liquid rubber prepared therefrom: wherein R, R1 to R4, and o, p, q and r are described herein.
Claims13
A method for preparing a liquid rubber, the method comprising a step S10:
- performing polymerization reaction of a conjugated diene-based monomer in the presence of an organic solvent and a catalyst composition, wherein
- the catalyst composition comprises a catalyst comprising a compound represented by the following Formula 1:
- in Formula 1,
- R is an alkyl group of 1 to 12 carbon atoms,
- R1 to R4 are each independently a halogen group, or a substituted or unsubstituted alkyl group of 1 to 20 carbon atoms, and
- o, p, q and r are each independently an integer of 1 to 5.
