Method of producing ionomeric polyvinyl butyral - Patent 4968745 (4737 words)
Plasticized polyvinyl butyral sheet is very well known as an interlayer for use with glass or rigid plastic panels in laminated safety glazing assemblies.
The polyvinyl butyral resin is more particularly partial polyvinyl butyral insofar as containing about 15 to about 30 percent by weight residual hydroxyl groups which promote adherence of the sheet to the glass or plastic.
Polyvinyl alcohol (PVOH) resin having a residual polyvinyl acetate content of less than 2% and a molecular weight of 23,000 was dissolved with agitation in water at 85.degree.-90.degree.
