The PDI (polydisersity index) is the ratio of weight to number - average molecular masses, M w̅ / M n̅ . In natural polymers, which are generally monodispersed, PDI is ............. and in synthetic polymers which are always polydispersed, PDI is ............. because M w̅ is always ............. than M n̅ . Fill in the blanks.
