The formation of macromolecular assemblies in solutions of side chain liquid crystal polymers, forming nematic mesophases in the melt, is investigated by dynamic isotropic and anisotropic light scattering for two molecular weights (65 and 286 kg/mol). The coexistence of single chains with supramolecular species is verified by examining dilute solutions in two different solvents. The shape and the overall dimensions of the macromolecular assemblies depend on molar weight and solvent. The high molar weight sample favors spherical aggregates versus the strongly non‐spherical structures of the low molar weight.
