End-modified conjugated diene polymer and method for preparing the same

One aspect of the present invention provides an end-modified conjugated diene polymer represented by Formula 1 below: 

The present invention relates to an alkylalkoxysilane compound of a novel structure which has an ether group and an dialkylamino group in an alkyl chain of the alkylalkoxysilane and thus has remarkably improved storage stability and hydrophilicity and a method for preparing same.

Alkylalkoxysilane compounds containing ether group and dialkylamino group and process for preparing the compounds

The present invention relates to a conjugated diene polymer end-modified with an alkoxysilane derivative. More particularly, the present invention relates to an end-modified conjugated diene polymer, wherein an alkoxysilane derivative having an ether group and a dialkylamino group is bonded as end modifier to an end of a conjugated diene polymer, which is useful as a rubber material for a tire tread owing to improved compatibility with an inorganic reinforcing agent and improves dynamic mechanical properties such as wet traction, rolling resistance, Mooney viscosity, processability, etc.

Conjugated diene polymer end-modified with alkoxysilane derivative

Disclosed is an interfacial polymer for a network used as a coupling agent in mixing of rubber-silica. More particularly, the interfacial polymer for a rubber-silica network is a block copolymer containing a copolymer of conjugated diene and vinyl aromatic monomers, in which when used as a coupling agent in the mixing of synthetic rubber and silica (an inorganic material), the polymer enhances silica dispersibility within the rubber, and improves compatibility and processability, resulting in considerable improvement in the dynamic property as well as the mechanical property of the rubber, and when used in a tire, etc., it enhances automobile braking performance and reduces rolling resistance.
