Abstract Block copolymers of methyl methacrylate and butyl methacrylate are characterized using silica adsorption chromatography with a toluene‐2‐butanone solvent gradient. Evaporative light scattering is the detection method for these otherwise hard to detect acrylic polymers. The homopolymer contamination in the diblock materials are well resolved from the diblock in the separation. The major separation mechanism is composition controlled, but the results also indicate a block length dependency on the separation mechanism.
