A film of Poly(alpha-methylstyrene)-block-poly(4-hydroxystyrene) blended with 20% (w/w) 4-[4-[1,1-Bis(4-hydroxyphenyl)ethyl]]-alpha,alpha-Dimethylbenzylphenol, a molecular glass. Terracing often occurs in block copolymer thin films when the film thickness is incommensurate with the thickness for a single morphology thickness, and in this case we see multiple terrace heights.
