The Method of Styren-Butadien Copolymer Using of The Coupling Agent of Acrylate Group And The Coupling Agent Thereof

摘要

The present invention relates to a silica with excellent affinity diene copolymers and methods for their preparation, more particularly a hydrocarbon solvent, under the Lewis base and an organic lithium catalyst, prepared by polymerizing a conjugated diene monomer and vinyl aromatic monomer Living polymer end the silica-friendly coupling agent polyethylene glycol acrylate copolymer thus prepared by the diene-based copolymer production method denatured using, the inorganic material of the silica and mixed using silica and silica in a solid by silica formulation affinity dispersibility is improved can be expected an effect that the workability and the physical properties of silica tires improved compared to conventional tires. ; Acrylate, coupling agent, styrene-butadiene copolymer
