Copolymer including functional monomer and method of preparing the same

One aspect of the present invention provides an end-modified conjugated diene polymer represented by Formula 1 below:  wherein p is a conjugated diene polymer chain; Rto Rare each independently C-Csaturated or unsaturated hydrocarbon chains; X is carbon (C), silicon (Si), or nitrogen (N); a is 1 or 2; and n is an integer of 1 to 200, and a method for preparing the same.

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

Disclosed is a conjugated diene random copolymer having an alkoxysilane unit, which is prepared by subjecting a conjugated diene monomer, an aromatic vinyl monomer and an alkoxysilane monomer having a specific structure to emulsion polymerization, and in which the copolymer contains an alkoxysilane unit in the backbone thereof and is thus enhanced in the degree of dispersion and affinity to an inorganic reinforcing material such as carbon black or silica, and is useful as a rubber material for tires having superior mechanical and dynamic properties.

Conjugated diene random copolymer having alkoxysilane unit

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 a terminal modifier for conjugated diene polymers. The terminal modifier has both at least two amine groups and at least one alkoxysilane group. A terminally modified conjugated diene polymer which is coupled at the terminus with the terminal modifier, and a polymer composition for use in tires, comprising the terminally modified, conjugated diene polymer are also provided. When applied to tire treads, the polymer composition comprising the terminally modified, conjugated diene polymer significantly increases the disperability and binding to rubber of silica, thereby greatly contributing to an improvement of the tire treads in dynamic properties including wet traction, rolling resistance, Mooney viscosity and processability.
