摘要： A polyvinyl alcohol polymer film includes a polyvinyl alcohol polymer and a plasticizer selected from the group consisting of ethylene glycol, glycerin, propylene glycol, diethylene glycol, diglycerin, triethylene glycol, tetraethylene glycol, and trimethylolpropane. The amount of the polyvinyl alcohol polymer eluted when a 10 cm square of the polyvinyl alcohol polymer film is left in 1 liter of water of 50° C. for 4 hours is from 1 to 100 ppm. The film has only a small number of defects and is useful as raw material for producing a polarization film.
