PROCESS FOR PRODUCING TRANSPARENT BLOCK COPOLYMER RESINS |
摘要 |
<p>PROCESS FOR PRODUCING TRANSPARENT BLOCK COPOLYMER RESINS A block copolymer resin having at one or both ends a copolymer block of a vinyl aromatic compound and a conjugated diene is obtained by subjecting a vinyl aromatic compound and a conjugated diene to 2or 3-stage block copolymerization in a hydrocarbon solvent in the presence of a definite amount of a Lewis base compound using an organolithium compound as an initiator. The block copolymer resin is high in transparency and excellent in mechanical properties, and is successfully usable in the fields of sheets, films and various molded articles.</p> |
