The microstructure and thermal stability of Langmuir‐Blodgett‐Kuhn multilayers containing rod‐like polyglutamate copolymers having flexible aliphatic side chains have been studied with x‐ray and neutron reflectometry. Upon annealing at 84°C the multilayer structure changes in a manner which is dependent upon the degree of orientation of the rod‐like backbones and therefore upon the flow dynamics of the deposition. A sample deposited with a highly convergent flow loses the bilayer structure induced by deposition, whereas samples with less highly aligned backbones may not undergo this relaxation as readily.
