Hydroxyl terminated poly (styrene-r-methyl methacrylate)(P (Sr-MMA)) random copolymers (RCPs), with molecular weight (M n) spanning from 1700 to 69 000 g mol− 1 and equal styrene unit content, were grafted at different temperatures onto a silicon oxide surface and subsequently used to study the orientation of nanodomains with respect to the substrate, in cylinder forming polystyrene-b-poly (methyl methacrylate)(PS-b-PMMA) block copolymer thin films. When the grafting temperature increases from 250 to 310 C, a ...
