【Abstract】 Polyvinyl alcohol is a kind of widely used polymer material, especially it can be used as excellent film or membrane. The recent situation and progress of study on modified polyvinyl alcohol used for barrier packaging film,instant water soluble packaging film, biologic degradation film and liquid mixture separation membrane are introduced, so the study of modified PVA used as films or membranes is quite active at home and abroad.更多还原
