Abstract
The in‐plane angular distribution of light scattered from a water supported monolayer of a diblock copolymer of polystyrene and polymethyl methacrylate has been measured. These data lead to the inference that the polymer molecules aggregate into discs with diameter 3800 Å, sensibly independent of surface coverage in the range 6.0–18.0 Å2/monomer. There is no sign of this aggregation in the monolayer isotherm.Keywords
