Abstract
Disclosed herein is 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 comprising a polymer wherein the surface tension of the polymer with the first polymer and the surface tension of the polymer with the second polymer are both lower than the surface tension between the first polymer and second polymer; where the additive polymer comprises a reactive functional moiety that forms a bond or a complex or a coordinate with the substrate upon being disposed on the substrate; where the reactive functional moiety is unreacted when it is a part of the composition; and a solvent.
