Block copolymer and method for producing same, composition for resin modification and modified resin composition, and method for producing same |
| abstract |
A block copolymer comprising at least one polymer block A comprising conjugated diene monomer units, and at least one polymer block B comprising conjugated diene monomer units and aromatic vinyl monomer units. This block copolymer is characterized in that (1) the polymer block A has a glass transition temperature of −88° C. to −45° C., (2) the polymer block B has a glass transition temperature of 30° C. to 90° C., (3) the content of aromatic vinyl monomer units in the whole block copolymer is 3-52 wt. %, (4) the aromatic vinyl block ratio in the whole block copolymer is smaller than 69 wt. %, and (5) the viscosity of a 5 wt. % solution of the block copolymer in styrene is 30-80 mPa·s. The block copolymer is useful as a resin modifier. |
