WebPolyvinyl butyral (or PVB) is a resin mostly used for applications that require strong binding, optical clarity, adhesion to many surfaces, toughness and flexibility. It is prepared from polyvinyl alcohol by reaction with butyraldehyde.The major application is laminated safety glass for automobile windshields. Trade names for PVB-films include KB PVB, Saflex, … Web4.2.5 Acetic acid and methyl acetate Acetic acid and methyl acetate are formed as by-products during the synthesis of PVA-PEG graft co-polymer. As shown in Table 1, levels of acetic acid in the three lots of the co-polymer tested ranged from 0.65-0.67%, and levels of vinyl acetate were below 20 mg/kg. 4.3 Analytical methods
