Title:
MODIFIED CONJUGATED DIENE-BASED POLYMER, METHOD FOR PRODUCING SAME, AND RUBBER COMPOSITION COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2021/066561
Kind Code:
A1
Abstract:
The present invention relates to a modified conjugated diene-based polymer, a method for producing same, and a rubber composition comprising same. The present invention relates to a modified conjugated diene-based polymer having a low hysteresis property and an improved fuel efficiency, and a rubber composition comprising same, in which the modified conjugated diene-based polymer is produced by continuous polymerization and thus has superb processability, and has a Mooney relaxation area of 300-1000 MU-s and a narrow molecular weight distribution of 1.7 or less, and tensile properties and viscoelastic properties thereof, specifically a tan δ value at a high temperature (60 ℃), among the viscoelastic properties, are improved when mixing the rubber composition.
