Zusammenfassung:	Methods for treating subterranean formations by diverting treatment fluids therein are provided. In one embodiment, the methods comprise: introducing a first diverter material comprising polyvinyl alcohol and a plasticizer into or adjacent to a permeable zone of a subterranean formation; introducing a second diverter material into or adjacent to the permeable zone of the subterranean formation, wherein at least a portion of the first diverter material comprises particles larger than particles of the second diverter material; and allowing the first diverter material and the second diverter material to at least partially divert at least a portion of a treatment fluid to a different portion of the subterranean formation.
