A neutral layer polymer compositions and methods directed self-assembly of

The present invention relates to novel polymer compositions comprising the novel polymer, the polymer having two or more repeating units and having the structure (1) end portions, wherein R1 represents a substituted or unsubstituted C1-C20 alkyl group, w is a number from 1-8, X is oxygen (O) or nitrogen (N), Rd is a reactive group. The present invention also relates to methods of using the novel polymer composition for forming a pattern. The present invention further relates to a method of preparing the novel polymer.
