Patent ID: 8491965

Claim:
A composition comprising: a mixture comprising: an orientation control component, comprising an epoxy-containing polymer comprising radically polymerized epoxy-containing monomers selected from the group consisting 2,3-epoxycyclohexyl (meth)acrylate, (2,3-epoxycyclohexy)methyl (meth)acrylate, 5,6-epoxynorbonene (meth)acrylate, epoxydicyclopentadienyl (meth)acrylate, and a combination comprising at least one of the foregoing; a block copolymer assembly component comprising a block copolymer that forms microphase-separated domains upon forming a film, and a solvent in which both the orientation control component and block copolymer assembly component are soluble, wherein the orientation control component is segregated from the block copolymer assembly component upon forming a film from the composition, and the orientation control component has an affinity for a surface of a substrate that is greater than the block copolymer assembly component's affinity for the surface of the substrate, such that the orientation control component is enriched at the surface of the substrate upon forming the film.
