    摘要: Disclosed herein is a formulation for depositing a cured underlayer for promoting the formation of self assembled structures. The underlayer comprises: (a) a polymer comprising at least one pendant vinyl ether monomer repeat unit having the structure, (I): wherein R is chosen from H, C1-C4 alkyl, or halogen, and W is a divalent group chosen from C1-C6 alkylene, C6-C20 arylene, benzylene, or C2-C20 alkyleneoxyalkylene; (ii) optional thermal acid generator; and (c) a solvent. The invention also relates to processes of forming a pattern using the underlayer.
