Disclosed herein is a method comprising disposing a mat composition on a surface of a semiconductor substrate; where the mat composition comprises a random copolymer comprising a first acrylate unit and a second unit; where the copolymer does not comprise a polystyrene or a polyepoxide; crosslinking the random copolymer; disposing a brush backfill composition on the substrate; such that the brush backfill composition and the mat composition alternate with each other; disposing on the brush backfill composition and on the mat composition a block copolymer that undergoes self assembly; and etching the block copolymer to create uniformly spaced channels in the semiconductor substrate.

to produce well‐defined linear polymers with one specific chain‐end functionality: OH, COOH or Amine. Using a postpolymerization reaction with functionalized azocompounds in a 5 to 1 ratio, α,ω‐telechelic polymers, with OH or COOH as functionalgroup at the second end were obtained. By using this synthetic strategy α,ω‐homotelechelic and heterotelechelic polymers were readily prepared. The chemical
