On page 2159, Jae‐Suk Lee and co‐workers investigate three kinds of bottlebrush polymethacrylates incorporated as random copolymer blocks for phase separation of polystyrene (PS) and poly(benzyl methacrylate) based‐bottlebrush block copolymers (BBCPs) with an extremely low χ parameter. The final BBCPs displayed ordered lamellar structures at 75%, 50%, and 25% mole ratios of incorporated poly(methyl methacrylate), poly(tert‐butyl methacrylate), and poly(methacrylic acid) in random copolymer block, respectively depending on the effective χ parameter of the PS and each polymethacrylate macromonomer. These bottlebrush block copolymers can provide a new synthetic approach as photonic bandgap materials. (DOI: 10.1002/pol.20200148 )
