BLOCK COPOLYMER |
| 摘要 |
A block copolymer, a method for preparing a block copolymer, a resin composition, and a film are provided. The block copolymer can be useful in inhibiting complete separation of the hard segment even under a severe high-temperature condition by increasing the chemical cross-linking density around the hard segment without causing an increase in glass transition temperature of the hard segment, thereby maintaining high-temperature durability. |

1. A block copolymer comprising:
a hard segment having a glass transition temperature of 25° C. or more; and a soft segment having a glass transition temperature of 10° C. or less, wherein the soft segment comprises a polymerization unit derived from a cross-linkable monomer, and the polymerization unit derived from the cross-linkable monomer has a higher concentration in a region adjacent to the hard segment than in a region which is not adjacent to the hard segment. |
