## Abstract The flow birefringence and the photoelastic effect in films have been used to study the molecular optical anisotropy of stereoisomers of polystyrene (PS), poly(__p__βmethyl styrene) (PMS), poly(methyl methacrylate) (PMMA), and polyβ(__n__βbutyl methacrylate) (PBMA). Considerable differe
