Abstract
The present application relates to a block copolymer and uses thereof. The present application can provide a block copolymer—which exhibits an excellent self-assembling property and thus can be used effectively in a variety of applications—and uses thereof.
Claims15
A block copolymer comprising a first block (that includes a side chain) and a second block (that is different from the first block), wherein X of Equation 1 below ranges from 2.5 to 10:
- X=1+(D×M)/(K×L) [Equation 1]
- where in the Equation 1, D represents a ratio (D2/D1) of a density (D2) of the second block to a density (D1) of the first block;
- M represents a ratio (M1/M2) of a molar mass (M1) of the first block to a molar mass (M2) of the second block;
- K represents a ratio (A2/A1) in a 1H-NMR spectrum of an area (A2) of a peak that is produced based on the second block to an area (A1) of a peak that is produced based on the first block;
- and
- L represents a ratio (H1/H2) of a number (H1) of hydrogen atoms in 1 mole of a repeat unit of the first block to a number (H2) of hydrogen atoms in 1 mole of a repeat unit of the second block.
A block copolymer comprising a first block (that includes a side chain) and a second block (that is different from the first block), wherein X of Equation 1 below ranges from 1.1 to 1.7:
- X=1+(D×M)/(K×L) [Equation 1]
- where in the Equation 1, D represents a ratio (D2/D1) of a density (D2) of the second block to a density (D1) of the first block;
- M represents a ratio (M1/M2) of a molar mass (M1) of the first block to a molar mass (M2) of the second block;
- K represents a ratio (A2/A1) in a 1H-NMR spectrum of an area (A2) of a peak that is produced based on the second block to an area (A1) of a peak that is produced based on the first block;
- and
- L represents a ratio (H1/H2) of a number (H1) of hydrogen atoms in 1 mole of a repeat unit of the first block to a number (H2) of hydrogen atoms in 1 mole of a repeat unit of the second block.
