Claim:
1. An article comprising: a brush polymer; where the brush polymer is reacted with a substrate upon which it is disposed; and a block copolymer; where the block copolymer comprises a first block and a second block that are covalently bonded to each other; where the first block comprises a first polymer and a second block comprises a second polymer; where the first polymer comprises less than or equal to 10 atomic percent of silicon; where the second polymer comprises at least 15 atomic percent silicon; where the brush polymer is chemically different from the first polymer and the second polymer; and where the first polymer is chemically different from the second polymer; and wherein the block copolymer is disposed upon the brush polymer; where the first block comprises a first polymer derived from o-methylstyrene, m-methylstyrene, o-ethylstyrene, m-ethylstyrene, p-ethylstyrene, α-methyl-p-methylstyrene, 2,4-dimethylstyrene, monochlorostyrene, 4-tert-butylstyrene, or a combination thereof.
