Abstract

An expression relating birefringence and the structure of ordered block copolymer materials formed under quiescent conditions was derived. The intensity of the light exiting the sample held between perfectly crossed polarizers was found to be directly proportional to the average grain size. The constant of proportionality depends only on material properties that could be obtained independently. Preliminary experiments support the validity of the simplifying assumptions invoked.
