    摘要： The present invention provides a process for producing a block copolymer in high productivity, by anionic polymerization by use of a lithium initiator, and also to provide the block copolymer and a hydrogenated product thereof, the block copolymer having a conjugated diene block portion with a high vinyl bond content and a vinyl aromatic block portion with a narrow molecular weight distribution and exhibiting a narrow molecular weight distribution and high strength. A conjugated diene monomer and a vinyl aromatic monomer by use of a lithium initiator, are block copolymerized by making a tertiary amine compound and (2) sodium alkoxide coexist, wherein (2)/(1) (a molar ratio)=from 0.01 or more to less than 0.1.

    摘要： A methacrylic resin having excellent impact resistance which is industrially more usable in general purposes, has the excellent weatherability and surface gloss inherent in methacrylic resins, and is optionally excellent in transparency and other properties. The impact-resistant methacrylic resin is characterized by being constituted of (A) a partially hydrogenated conjugated diene polymer having a degree of hydrogenation of from 20% to 70%, excluding 70%, and (B) a methacrylic copolymer formed from from 80 to 99.9% by weight-methyl methacrylate and from 0.1 to 20% by weight at least one other vinyl monomer-copolymerizable with the methyl methacrylate, and by having a toluene-insoluble content of from 0.5 to 50% by weight and a degree of swelling in toluene of from 2 to 12.
