| titleOfInvention | METHOD FOR PRODUCTION OF A MODIFIED POLYMER OR A HYDROGENATED PRODUCT THEREOF |
| abstract | METHOD FOR PRODUCTION OF A MODIFIED POLYMER OR A HYDROGENATED PRODUCT THEREOF. A method for manufacturing a modified polymer or a hydrogen adduct thereof is provided, the method allowing the components, which inhibit polymerization, to be removed, and the remaining part to be reused as a polymerization solvent. . The method involves the manufacture of a modified polymer having at least one functional group on a main chain or a side chain, obtained through polymerization with a conjugated diene and/or a vinyl aromatic compound as the monomer and an active organic metal as the the polymerization initiator, in the presence of a hydrocarbon-based solvent, which is used as the polymerization solvent; or the manufacture of a hydrogen adduct from the modified polymer. The method comprises, in sequence: (a) a solvent removal step to separate the reaction solution, wherein the modified polymer or hydrogen adduct is dissolved in the polymerization solvent, in a solvent fraction containing the solvent hydrocarbon-based and a solid fraction containing the modified polymer, or the like; (b) a low boiling fraction separation step to distill the solvent fraction and separate the hydrocarbon solvent from the low boiling fraction containing a silanol compound; and (c) a silanol removal step to remove at least a portion of the silanol compound from the low boiling fraction by liquid-liquid extraction using the low boiling fraction and an extraction solvent. In addition, at least a portion of the extract solution, in which the silanol compound has been removed by liquid-liquid extraction, is reused as a polymerization solvent. |
