High resolution Brillouin spectroscopy (BS) has been used to investigate elastic and optical properties of uniaxially drawn samples of polycarbonate (PC). The results are discussed in the framework of the single phase aggregate model (SPAM) of Ward. According to a recently developed evaluation technique, the SPAM parameters of PC are determined, resulting in the following elastic constants of the structural units:c330=33 GPa,c110=7 GPa,c130=9.7 GPa,c440=1.4 GPa, andc660=1 GPa. A nearly quadratic dependence of the orientation parameterP4 onP3 results, which can be explained by a modified pseudoaffine deformation scheme.
