Zusammenfassung:	Methods for improving the dispersion of optical brighteners in polymeric compositions are provided. Polymeric compositions obtained by these methods are also provided. Premixes for use in the methods are also provided. In particular, methods for incorporating an optical brightener in a polymeric composition comprising dissolving the optical brightener in a solvent prior to adding the optical brightener to the polymeric compositions are provided.
