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.
Claims2
A liquid rubber comprising a conjugated diene-based monomer unit solely, or a conjugated diene-based monomer unit and an aromatic vinyl-based monomer unit, wherein
- a number average molecular weight is less than 100,000 g/mol,
- the liquid rubber is present in a liquid state at room temperature (23° C.±3° C.), and
- in case of comprising the conjugated diene-based monomer unit solely, a trans-1,4 bond ratio of the conjugated diene-based monomer unit is 75% or more, a cis-1,4 bond ratio is 1% or less, and other bonds are 1,2-bonds.
