Abstract:
Disclosed herein is a method comprising disposing upon a substrate a composition comprising a block copolymer; where the block copolymer comprises a first polymer and a second polymer; where the first polymer and the second polymer of the block copolymer are different from each other and the block copolymer forms a phase separated structure; an additive polymer; where the additive polymer comprises a reactive moiety that is operative to react with a substrate upon which it is disposed; and where the additive polymer comprises a homopolymer that is the chemically and structurally the same as one of the polymers in the block copolymer or where the additive polymer comprises a random copolymer that has a preferential interaction with one of the blocks of the block copolymers; and a solvent; and annealing the composition.
