SILICA WITH POLYMER BRUSH AND MANUFACTURING METHOD THEREOF

摘要

A silica having a polymer brush and a manufacturing method of the same are provided to improve dispersibility and miscibility of an organic material and silica by converting surface chemistry property of the silica into organophilic. A manufacturing method of silica having a polymer brush comprises the following steps: a polymerization initiation preparing step injecting the silica reformed with a solvent and a vinyl group; a reaction initiating step performing reaction by injecting an anionic polymerization initiator into a reactor; a graft step grafting the brush by polymerizing conjugated diene monomers; and a stopping step halting the reaction by injecting a polymerization terminating agent into the reactor.
