Document Type and Number:
WIPO Patent Application WO/2022/215986
Kind Code:
A1
Abstract:
The present invention relates to a liquid butadiene compound with both ends modified, a method for preparing same, and a use thereof. More specifically, the present invention provides a liquid butadiene rubber compound with both ends modified that is synthesized using a chain transfer agent having a triethoxysilyl functional group and a tetrasulfide functional group, and a 1,3-butadiene monomer, a rubber composition for a tire comprising same, a method for preparing same, and the like. According to the present invention, by introducing a silica-friendly functional group at both ends of the chain, hysteresis or the like caused by the chain ends of an existing liquid butadiene rubber is controlled, and thus, various performances affecting fuel efficiency characteristics can be improved.
