Triblock brush block copolymers

A brush block copolymer comprising:

• a first polymer block comprising at least 3 first repeating units, wherein each of said first repeating units of said first polymer block comprises a first polymer backbone group directly or indirectly covalently linked to a first polymer side chain group;
• a second polymer block comprising at least 3 second repeating units;
• wherein each of said second repeating units of said second polymer block comprises a second polymer backbone group directly or indirectly covalently linked to a second polymer side chain group;
• and
• a third polymer block comprising at least 3 third repeating units;
• wherein each of said third repeating units of said third polymer block comprises a third polymer backbone group directly or indirectly covalently linked to a third polymer side chain group;
• wherein said second polymer block is directly or indirectly covalently linked to both said first polymer block and said third polymer block along a backbone and said second polymer block is positioned between said first polymer block and said third polymer block;
• wherein said first polymer block, said second polymer block and said third polymer block are characterized by a chain grafting density equal to 100%;
• and
• wherein said brush block copolymer is defined by the formula (FX11):
• wherein Q1 is said first backbone terminating group and Q2 is said second backbone terminating group;
• r is an integer selected from the range of 1 to 5;
• wherein m, n and p are each independently an integer selected from the range of 3 to 1000;
• wherein x, y and z are each independently an integer selected from the range of 3 to 100.
