ACRYLATE-BASED COUPLING AGENT CAPABLE OF PRODUCING A SILICA FRIENDLY STYRENE-BUTADIENE COPOLYMER, AND A PRODUCING METHOD OF THE STYRENE-BUTADIENE COPOLYMER USING THEREOF

摘要

PURPOSE: An acrylate-based coupling agent and a producing method of a styrene-butadiene copolymer using thereof are provided to remarkably improve the dispersibility of the styrene-butadiene copolymer for an inorganic filler including carbon black.;CONSTITUTION: An acrylate-based coupling agent for producing a styrene-butadiene copolymer is marked with chemical formula 1. In the chemical formula 1, n is an integer of 1~100. A producing method of the styrene-butadiene copolymer comprises the following steps: forming a living polymer by polymerizing a conjugated diene-based monomer or a vinyl aromatic monomer under the presence of an organic lithium catalyst; and coupling the living polymer using the acrylate-based coupling agent.;COPYRIGHT KIPO 2010
